Yup yup. RedEvil, you and ASG14 were right at Clay's place. The noise coming from my engine looks to be indeed the timing chain. The chain itself is *alright* from my perspective now with the valve cover off, but the left hand chain guide is completely worn through to the metal. That would explain the noise. Bad news is this means I have to pull the front cover to replace it, which involves taking off the head, forward oil pan bolts, etc. A lot of work. Fun times! At least now I can replace my headgasket whether I needed to or not...


This whole thing is disturbing since the motor only has about 5000 miles since its rebuild.

Edit: Not only that, but I just found out the crankshaft pulley is rotating several degrees SEPARATE from the crankshaft... wtf...

I would have done that a long time ago but the seller wanted $2500 for it... and then later sold it to some kid for $1900.

Edit: oh sorry, $1850 :P

Dude, I'm so sorry for being right this time!

Edit..

When I did the chain and guides on my s30 (l28e) I didn't have to touch the head, why does yours have to come off?

Because I'm taking apart the front cover, and I suspect my engine is consuming coolant since it emits white vapor while it warms up. Coolant in my rad also looked like it had "oily" bubbles in it, so I suspected the head gasket. There's no coolant in my oil though, so my theory is that its rich exhaust gasses getting into a coolant passage. Or a crack in the head somewhere. Regardless, I want it to have ARP head studs on it. One of those "while I'm at it" things.

No, (probably) a standard Nissan turbo head gasket. The current gasket I believe is a Nismo metal one. It seems like most of the opinions on HybridZ point towards using the standard gasket with ARP bolts for the best mix of performance and reliability. That is, unless you're running a ton of boost in a >400hp car that's regularly thrashed. 400hp is the absolute maximum I ever plan to push through this car, 350 being a more realistic goal.

Edit: another reason for the Nissan head gasket: its better than the Felpro one and still costs under $50. Since I just dumped about $500 total for ARP's, timing set, harmonic damper etc, I'd rather not spend another $150-$250 on a metal head gasket. I have no idea what the condition of the head and block surfaces are either. If there's any imperfections at all the bead style metal gaskets tend to leak, possibly why mine is (if it is).

Destroyed woodruff keyway.

Timing chain guide worn through to the metal.

Pitted cylinder bores (hard to see and blurry, but its worse than it looks).

Stock pulley; Cracked and DONE.


New stuff for replacement and improving.

Both local machine shops are quoting me about $300-$500 depending on what I want done, including the boring, cleaning, magnaflux inspection, possible balancing and polishing. Crank needs to be inspected for cracks, block is getting a .020 overbore to clean up the pitting in a few of the bores. Wheeee....
