I performed the leak down test.
Made my own. Many of you will be happy to know, you do not need to use a hollowed and threaded spark plug, but can us a 3/8 compression fitting (brass)w/the nut removed. The threads are very similar to the sparkplug's thread, allowing the 1st three threads to fit nice and tight enough(just hand tightened). I may do a write up when I'm done. Cost me $55, all from home depot.

I found one cylinder to be leaking on the exhaust side w/ air coming out of the tailpipe, and then another cylinder to leaking through the intake side w/ air coming out of the tube next to the suction pump/pcv/y shaped fitting: which seemed strange to me seeing that the intake cam was only slightly off by one tooth.


both cams are out, and I am at TDC with locking pin in crank. I believe this should bring all the valves to a closed position, therefore establishing a leak to be on valves.

Anybody know where (online) to find valves to buy???

I guess I will remove the head and take it into the machine shop. I called them already they said bring it in, I would supply the valves, he would estimate cost to repair. I am assuming I simply need to remove the 8 head bolts and the exhaust manifold and it will pull up-and-out!?!

What in the hell is a 4352 Polydrive - special tool. Can I find a similar 12 pointed long bit to remove the head bolts?

Get the right tool. My local NAPA got it next day.

We've got you covered on the tools and the valves - click here for pricing and details.

With the cams out and the intake and exhaust off you just have to remove the head bolts. Remember, you should use new head bolts when re-assembling!

whats the diff between the $9-13 valves vs the $29 valves? sodium?

aren't sodium stock on the 30v?

is there anything else needed for valve replacement?

Pete@ECSTuning

Oh woops, missed the 30v mark, my bad - click here for pricing and details on 30v valvetrain. It is a completely different set of valves.

Hey guys,

took the head to the machine shop, replaced two exhaust valves in the same cylinder.

Started the job at about 6:30 Thursday night, worked through the night, finished this morning. cleared original codes. started up fine, with no codes the first time. I just have to put the bumper on now. it sounds very smooth.

i can't wait to drive it today. I'm driving up to my families camp for a memorial weekend camp and pig roast. Its about 2.5 hrs away. Nothing like a short road trip to test it for stress factors.

Thanks for help on this. I really appreciate the guidance and insight. Have a great weekend.
