got my engine running but not good at all

[anthony90si]

ya i am gonna take a look at the timig chain tonigt. hopefully it is just that. but i ahve a feeling that there is more too it. the head was replaced so maybe there is something wrong with it, i dunno. and i really doubt that the exhaust is blocked. it only has the stock resonator with a strait pipe.so i doubt that would be the problem. lol
thanks guys i will let you know what happens.

[anthony90si]

hey guys i took a look at the check engine light it i found the codes 5,6,11,12. what the heck does this mean. it can't be that good..

[Brian R.]

I don't think those codes mean anything until you have correct valve timing. Like 4Wheel said, fix the big problem (along with your ignition timing if it is off) and then erase the codes and see if they reoccur.

[4Wheel]

You'll be wasting a lot of time and money chasing those codes unless you get that engine running better. forget the codes right now, what is your compression. Reading those codes is like taking the pulse on a body with no head.

I can't get past the fact that there is excessive blow-by. This is a major issue especially with an engine that just had a major performed. The codes that will be logged may well be erroneous due to the mechanical issues, air fuel mixtures that the ECU has attempted to automatically correct.
The codes are generated with a best effort algorithm assuming that everything else is sound, crank and cam aligned properly.
Blow-by, if there is an excessive amount or more than there was before the head gasket job is a mechanical problem nothing electrical/electronic will cause this. Plus running an engine with an improperly timed cams can result in more damage.
This is difficult to do without being there. So start at the basics with the items that need to be looked at without the engine running.
A quick compression check will tell you a lot, it will even explain a rough idle and blow by if it’s worn rings but you say it ran fine before.
Check the timing belt timing it doesn’t take too much work to get the covers off just the damper will require a puller sometimes.
This is the easiest: check the MAF on top the air cleaner make sure it is not binding and the rest of the intake conduit, free of blockages clean air filter.
Exhaust, how old? Not blocked? Had a muffler fall apart internally and the pieces collapsed the exit tube it caused a lot of backpressure.
Just some ideas “in the dark”
Brin R. and Angella always have good sound suggestions, so keep trying, keep asking.
Good luck keep us posted when you find out.

ya thats true. i took a look at the timing chain and it seams to be off half a link. is that possible. also there seems to be a loose in it like when i turn the crank the cam doesn't follow right away.i would say that i have to turn the crank about an inch befor there is any movement from the cam. so can that be the problem.. also for the compression i got a cheapo from walmart, and it sux lol. i can't get it to have a decent seal with the head. i did get a reading on the number one cylinder and it was around 110. i wasn't enough place to look at the other ones(i have to get a better tester).so i would assume that the psi would be a bit higher.

Reset the timing chain so the marks all line up as they are supposed to. Also, sounds like the chain tensioner is not doing its job. Check it for binding and tension.

so is that a whole other problem or could a half a notch be cause the problem

[Brian R.]

I think they are related.

Sounds like your trying to turn the engine the worng direction clockwise only. Only ever then recheck the alignment marks.

ya i was turning it both ways . if i turn it colckwise the mark on the cam is pointing a bit towards the left. is there a way to check the chain with out looking at the links of the chain. lets say by setting the crank pully to 0 and set the cam in a certain direction.
thanks

[4Wheel]

Did you say the chain was new?
There should be no "play" in the links it's hard to actually see but there would have to be a lot of "play" to make a difference at the cam.
When turning the engine manualy always turn so the tension is between the crank and the cam not through the tensioner.

ya its new. it cause i was turning the crank the wrong way. so if the crank is set to 0. where is the mark supposed to be on the cam gear

[4Wheel]

You will want to consult the manual for this for you exact engine and year. I do even when i "KNOW" then I take a picture just so when you start talking yourself into that it must be wrong all you have to do is look at the picture!

Good luck

ya well all it tells me is that i have to ligne up the links with the marked ones on the chain. so i have to take the timing cover off. or i am gonna see if i can find anyone who know these engines well

[4Wheel]

well that is all you will need, you will find two marks on teh chain those marks should coincide with the "dimples" or "marks" on the cam and crank sprockets.
