Wel i have the timing belt off so i can't really do a compression test. Man this is fucking annoying. I'm totally stumped.

[blk_srt]

do a leakage test then, all you have to do is make sure the valves are closed, that will tell you just as much

[ez1286]

don't i need a tester for that? do you know where i can get one?

[gthompson97]

I believe that was myself that was the first to say do a compression test, but yet no one listens to me. I agree with Kevin (and probably everyone else on the forum) that your problem isn't caused by the oil pump or any sort of "excessive pressure."

The leakage tester isn't really a "tester", it's more of a machine that puts pressure into the cylinder and you figure out where the leak is.

You should always check the timing when you're having problems with the car running, it's not hard for timing to jump, especially after you change something major that directly affects timing (cams and/or cam gears). Just because it was right on before and during doesn't mean it didn't change after. NEVER assume timing is good.

I checked the timing and it was right on. I didn't want to do a compression test because i didn't want to cause further damage to the engine if it was in fact bent valves.

all a leakage tester is, is a air regulator with a gauge on each side of the valve and you screw it in just like a comp test but it puts air in and tells you the % that is leaking out. I'm sure they sell them at parts stores

Come on dude, you don't seriously believe what you just typed do you?

[ez1286]

Haha i ddn't even ealize i said that, i meant i didn't want to cause further damage in the engine. Give me a break i had worked on the car for like 10 hours at that point. See my other post in problem diag...

[gthompson97]

You couldn't have possibly done more damage to the car even if there was originally something wrong, you would have done the most damage that you could do by driving it. A compression test wouldn't cause any more damage. Sounds like a bit of lazyness to me.

[ez1286]

laziness? I just tore the whole engine apart!!! Go fuck yourself!! J/P. No i was really concerned that the oil pressure was going to fuck the bearings but now i know better i still need to replace them so oh well. Time to stroke off (or on depending on you're opinion). Anyway I discovered all the aluminum in the oil pan and the intake valves tapped to cylinders (it must have been off a tooth and i couldn't tell). So the plan is to stroke with 1mm oversived valves and dual springs. That should be a beast.

if you dont mind only revving to 7k, me, I'm going with a destroker and be revving to 10k

[ez1286]

Meh how often are you actually going to want to rev to 10k? 7k is fine for me, i'll probably get a 60trim at the smallest. So when you're turbo spools at 7500rpms i hope you're happy

[kjewer1]

I ran my stroker to 8500.

Also keep in mind that larger valves are more likely to crash into shit You'll have to be even more careful.

[Thor06]

I dont know why, but that made me laugh. I think I remember reading that the O/S valves dont really do much for you until you are flowing 50 lbs/min or more. After reading about them when I was planning what I would have to do to my head, I decided against them.

[ez1286]

Hmm.. maybe i wont go for oversized valves. I really haven't done a lot of research on engines yet but i plan for about 500hp, so i'll plan accordingly.
