Yeah, but to get enough to make contact with aftermarket pistons like wisecos if thats what I'm reading right? Thats nearly insane. They have larger valve reliefs.

 

I wouldent doubt that its possible more so on the lnf due to the cam phasers

 

Alright boys and girls, looks like i could have solved my problems a bit sooner.

I'll just come out and say it appears to have been a stretched timing chain. I had bought a new one, took it home and hung both of them from a rod. They looked almost impossible to see a difference in, maybe 1mm-3mm difference. So i reused my other one thinking i bought the timing chain for no reason.

After getting fed up i put the new chain on and everything felt much much tighter. It was even more difficult to take off. I can't see where the old chain is stretched and even when i compared them again in length they looked so damn similar.

Yet going back to back with chains and no other changes one would slip and the other wouldn't. I even swapped em back while turning by hand to confirm. So yeah 1-3mm changes things.

 

Good info. Thanks for sharing.

 

Ahh, so that was the problem. I believe the same thing happened to my buddies GTI when his timing chain failed. The timing chain was stretched and caused it to jump and crushed the valves.

 

1mm=.039 did you look at the chain oiler if you did did you see how small the chain oiling hole was gm on the race engines made that hole bigger how much I don't know but the extra oil lubricating the chain and helping keep it cooler couldent hurt

 

Ford what do you have your redline set to?

Do you know the spring wastegate pressure of our s256et kit?

 

Redline is 7400.

 

Take the boost controller off and do a pull.

 

Ha....or I could take five minutes and Google it...

 

I would think 1 bar but I guess who knows what spring they provide.

 

kits sold now have larger orifice chain oilers. I thought you knew that.

 

considering they dident offer kits when I bought chains gears and sliders so no I dident know that I just modded the ones I use. tom sent me an email with a link one day not long after I bought all me stuff and said hey what do you think of this he said it was my fault for the kits lol

 

How much is this chain kit? It looks like I should be replacing mind at some point just as a preventive maintenance?
One thing that I don't do often is hitting my rev limiter - maybe on 2 occasions accidentally.

 

Nice! Glad you got her fixed up man. I had replace dmy chain as you did and found the same indiscernible difference in length as well but by then I guess the damage was done cause the the new chain didnt change things in my case.

I did however get an all new kit from CLOYTES when I put the new head on and the oiler they include does indeed have a slighler wider diameter oil squirter. In any case, glad you got her running again

 

Thanks.

Now im just struggling with if i just want to forge or go with a girdled block as well to reach my next power goals. Trying to talk my buddy with a SRT4 into buying a manifold and taking my turbo.

 

Yeah, there shouldn't be hardly any slack. Thats how you tell if you need a chain if your tensioner isn't bad. Had the same issue with my friends LSJ. But also bad tensioners can cause your chain to stretch.

 

thank you for all this, I have learned pretty much that its my tensioner, going to try that over in the LSJ forum I have a post about my fresh built forged engine wont start. Ended up starting but now I have ticking.

 

Go E85 and you'll hit your rev limiter quite easily, xD

 

I really wouldnt mind having solid cam gears. To avoid all this lol.

 

Lol, it wouldn't be hard to make a set. But then someone would have to machine plugs for the vvt solenoids as well so there isn't oil pressure being fed through the cams. Deletion of a few mils in hpt and I see no issue.
