GTO engine problem

I know some of you are sick of my remarks about the Chevy GTO, but you have to make a gut check to see what kinda car person you are.

The cars engine is the sole of the car, the car should be built around the engine, not the other way.

If it's ok to just put any engine in any car, would be buy a Jag with a SBC? Would you buy a Vette with a Jap engine? If you the type that thinks the power numbers is all you want then you should have no problem with any engine that makes power.You just like the outside, and it's fast!?

The new Chevy Ause GTO is just this, it has a SBC based engine in it, and a few pontiac arrow heads on it, does that make it a Pontiac? NO, LOL it dosnt even have anything PONTIAC on it! Just the arrow heads?!

For those who love this car you are not true motor heads, your they people who go for the looks then the speed, and I feel sorry for you because you dont have the depth that the others have, the feeling of the history of the engine and the body they gave to rep the engine.

Even if this car had a pontiac engine in it, it would still not be a GTO with the body being made in another country! So what you have is a Chevy history (the engine) in a non American body...

I'm I the only one here that sees a problem with this?

I'm not trying to start a fight, you have to look at it this way, the GTO was a american made car with a engine with roots from the 50s, the Pontiac Chevy wars were real!

Take a drag race, why have Chevy VS Dodge? what have a race? is it engine VS engine and driver or is paint job and driver? Is it getting clearer?

Why dont we make an engein for everyone for every car? we will call it the UEFE Universal Engine For Everyone, it would be a V10 and depending on how you ordered you car you could have 2 to 10 cylinders working from the factory, you could be upgrads that got you more cylinders. So when you goto the car shows and track meets, you all could brag about your UEFE and everyone could be the same Mr. Gasket Chrome kit! wow sounds fun (NOT). When you drag race all you have to say is my UEFE is faster then your UEFE, gone are the days of saying "Your Slowpar is junk" of your "Slowsmobile is draging parts". Now it would be I bought the super 8 kit, you only have 4..... how lame is that, sounds stupid? It's been going on for years, the same SBC in all those F bodys Pontiac and Chevy, it's allways been Chevy VS Chevy....

If I was to pull up in my GTO next to a ChevyAus GTO I would be raceing a bastard Chevy, not a Pontiac.

How about this, a Firehawk VS a same year SS factory no mods, it's going to be chevy VS chevy... or to some of you my cool car vs your ugly car!???? what a boring idea.

Is it the looks first? Is it the engine first? Is it the Name First?

It's a good question for all of you, and it lets everyone know what level of car person you are. Does anybody still race engine makers anymore? or all of you raceing paint jobs?

Well, this is certainly a controversial topic... First, let's dispel the myth that LSx is a Chevy. It is not. The ONLY two part numbers that it shares with small block are the rod bearings and the lifters. And those lifters are in ALL the GM hydraulic roller/pushrod engines. Even the rods themselves, are different than the small block. LSx is simply the "next generation" GM corporate V8. It shares zero design features with SBC. It makes GTO much less of a Cheviac than the last itterations of F-bodies equipped with real 350s.
GTO is fast. Regardless of how you wish to look at it, it will go low 13s right off the showroom floor (seen it at Pontiacs In The Park!). It is an intermediate-sized car with a large engine. Sounds like pure "muscle car" to me.
Crying about the world market and imports won't change a thing. GM is GM. They have the right to sell their products any way they see fit. I too, would rather see a domestically produced GTO. But an Aussie-built GTO is better than no GTO at all!
Just my take...

BTW, where does that name come from? There were no Ram Air cars in '72... Just "HO". Do you have a modified '72? What motor? Rear? Performance? I always liked the look of '72 over '71. Something about the mesh in the grills in the '71 put me off. The "blackout" grill fits the scheme a lot better. Purty cars...

You just don't get it.... There are no more Chevy or Buick or Pontiac engines. All of GM's engines are GM Corporate engines! Quit trying to change it.

And another thing, GM only designs and manufactures automatic transmissions. All of the manual transmissions with exception to the transmissions in the heavy duty trucks (Allison) are built by suppliers.

The uniqueness of a powertrain in any platform are the calibrations, the gear ratios used, and the logo on the fuel rail covers.

Quit living and thinking from the 60's.... It's 2005.

First off I would like to thank everyone for writeing in, hopefuly we can keep our "beliefs" from getting into name calling.

Ok, you have to look at the history of the SBC to know that what is now in the engine bay of that AusChevGTO is really I Chevy engine...Your correct about the engine it's not the same 50-60s SBC however it is what the SBC should be for this time period! It is a SBC with modern changes, even tho the heads on that engine don't fit a reg SBC for say, but if you tryed to place a Pontiac head or a Olds head next to it you will find that the new head matches to close to the orignal SBC head.

People it's not apples and oranges, it's McINTOSH and GOLDEN DELICIOUS they are the same family, it's just GM ran with it and saved money by making one engine that fits all makes!The engine has more in common with a 60-70-80-90s SBC then any other engine anyplace, but you tell me it does not come from it!!!!??? IT IS A SBC BY FAMILY! If you can't see this then your in denial and your allways going to refuse the truth about this engine. Ask yourself how hard it would be to put a set of rods from AusChevyGTO engine into a reg SBC, hmm not so hard it your tryed to put them in a Olds, run with that feeling you just had, its truth knocking!

It's not that i'm trying to live the 60-70s I just think that a one size fits all engine no less made by Chevy should have the honor of being called a GTO in the Pontiac Family, the inner company wars on engines in GM is what made you buy a GTO or a SS, or a 442, IT MAKS NO SENSE TO RACE BODY STYLES, because thats what your doing, oh yea I say that as a whole, i'm argueing about suspession types or they way they power is sent to the ground..

It's a Fake, the engines family is SBC and the body/chassis comes from another country, so not only are you putting Americans out of work YOUR making a BASTARD out of an AMERIAN LEGEND! Thats TRUTH!

I think you should brush up on your GTOs, even tho the GTO was droped to a "Option" in 1972 it's still a GTO, I would say that it was the last real GTO, becasue the next few were ummm ugly and slow. RAM air engines were still being made past 1972 infact very little was changed in some RAM AIR heads like say a 6X head , it's really a RAM AIR head with a small Ex valve and more CCs! My heads are not correct for the year of the car, they are 1970 #13 that have been ported and shaved, the Car is a GTO however the parts that were needed to rebuild it mostly came from a Sport Lemans, or they are VFN fiberglass, my car is on page 7 of VFNs webpage, I guess thats what you get when you spend thousands in carbonfiber/glass parts.

The 1971 GTO has mesh "egg crate" flush with the endura, and they have no air extractors . the 1972 GTO has the same hood and "deep egg crate" along with air extractors,they worked,it's not a show piece like most other cars. It looks like it's going 100mph sitting still, and it does not have a one size fits all engine. My engine right now is makeing around 475HP however i'm collecting parts for the GEN2 IA block 600+ with Tiger Heads that flow stupid numbers, oh yes it's going to be forced induction.

Thats another thing, RAMAIR 7, what a buch of BS it has nothing to do with what PMD made , but now they slap it on that BAstaRD in hopes of sucking in people, why not go all the way and call it a SS RAM AIR R/T HEMI!!! it's all BS and SOME people are eating it up.

SOOOOO WWWWHHHHHAAATTTTTT if its fast!!!!!!!!!!! you can make a VW do 9s!!?!!?!?!?!?!?!

By the way "rzkz8k" i'm 30 not 58,I love FI and computers in cars,
I just have Brand LOYALTY AND INTEGRITY.

Hi
I own a 1972 Pontiac GTO 455 HO, from some time the oil pressure gauge showing very low pressure i noticed this after we have made an oil and filter change, it is puzzling me!!

I've changed the sensor but still no difference, do you guys have any suggestions??

Thanks in advance
Tony

Pbody would be the better one to reply, however I will toss in my 2 cents.

Is the engine rebuilt? been rebuilt? If it has some of the clearances may have been off, or you blew out a oil plug.
If the engine is old you may just need a rebuild, or you blew out a oil plug. many things could have happend, if the car was raced/reved it could have somthing to do with it.

I used to change oil for a while, if it happend right after you changed the oil, check to see if you dubble gasketed the oil filter, somtimes the gasket from the oil filter comes off the filter and sticked to the oil filter houseing, when you put the new filter on you now have 2 gaskets and problems happen.

If you find the problem please write back.

[MrPbody]

Did you use the same oil and filter combination as usual?
How many miles on the engine? List any deviations from the "norm" that may have occurred during this past change period.

[Hurst]

Hi guys,
Thanks for the replies.
Well, the engine it's not rebuild and not old, actually only piston rings were changed once long time ago, the car was not raced but YES it was reved, i can't see any oil leakage from the engine.
I used original GM filters P24 (i think so) and i used mobil 20 - 50 since i have hydrolic lifters.

the car has almost 62000 miles on it (we kinda try to preserve it).
deviations from norm.. well the carb needs some tune up, but i cant see anything else, i'll check the car on the week - end and post.

btw, nice forums

[Hurst]

Hi

Ichecked the Oil filter and it's no double gasketed. :/
some guy told me that it might be hmmmmm (forgot what's called arrrgh) those things that mount between the cranckshaft's polished part and the block.
Damn my memory has holes in it!! like swiss cheese

Tony

bearings

If you reved it to high you could have moved one, or spun one or even stacked one stacking one would have loud sounds comming from your engine.

It's not good, the best thing to do is have sombody that rebuilds engines look at it, if it is a bearing you may be able to save it with out much cost. (New bearings)

I'm sorry this is not better news, Pontiacs are very good engines, however they do not and can not be reved to high unless you have some money in the engine as far as parts go. This is the reason so many people goto the "Dark Side" also known as Chevy.....

I hate to say it's a crank bearing and have it be a cam bearing or rod, you must have it checked before it shows you its parts without opening the engine up.

It's a shame it got over reved, If Pontiac was not given such a tight gap for HP engine stuff by GM because Chevy don't like it's cars beat up, things would have been better and you may have not had a problem.

If it is a rod bearing problem try to figure out who reringed what piston, if the rod bearing went on the same rod and piston you will have someone to be upset to.

Good luck I hope this helped

Hi

We've checked the engine and doesn't seem to be a bearing sound or a push rods, the engine's sound is VERY smooth. everything seems very normal. it was revved once but it didn't go over the redline.

I dont want to disassemble the engine.
do you think I should change the Oil pump first?
80 psi oil pump is used on it.

Ok, I will first try to remove the valve covers and see if oil is being pumped to the upper block of the engine.

will post soon!

Thanks for your help man!! really apreciate it

Cheers!!
Tony

PS: soon post a pic of my goat too

[MrPbody]

The relief valve ion the pump MAY be hanging up. It's a 5/8" diameter ball bearing. The bore it rides in is only a fwe thousandths bigger. A small piece of debris can hang it up.
Replacing the pump will eliminate this as a cause, but I highly recommedn the 60 lb. pump. The Ram Air IV pump (80 lb.) adds strain to the distributor gear and the oil pump driveshaft. For a street-driven engine, 60 is plenty.
If you replace the pump and no change, pull the engine. Check cam bearings and main bearings.
It's also a "remote" possibility, one of the pressed-in oil gallery plugs in the front of the block has popped put. It doesn't happen often, but it DOES happen.

Jim,

Thanks for the advice, i'll do those checkings this week-end, i hope the problem will be solved.

Cheers!
