Sure others here would know more but I think its either really high heat or excessive fuel. What did those two spark plugs look like?

The two plugs were both soaking wet with oil, which was the first sign that I knew I had major block issues.

I defer to the experts on that one. To me it looks more carbon fouled than oil fouled. It looks dry and baked on, but I trust you when you say it was oily. What if those two injectors were stuck open, pissing fuel the whole time and washing the oil off of the cylinder walls, thereby allowing the rings to scratch them due to lack of lubrication?

Then the scratches let excessive oil blow by and...well you get the idea.

Eh, I would notice that on 2 cylinders. The car ran too smooth for that to be happening. Plus nothing was wonky about my wideband readings either. My wideband was on this bank BTW. The tune was pretty much dead on from before.

Says carbon fouled plugs can result from low compression too.

I have a brush research ball hone you can use. Just stroke that bad boy up and down till the sratches are gone. then re-assemble and go. You may get a little piston slap on those two holes so install a louder stereo at same time.

I would never do something like that outside in the dirt (unless it was at the dirt track) and my HOA would have my ass for even trying.

At least you're a phillies fan. The pain you're experiencing right now should be nothing compared to that debacle of a season

The fact that they won it in 2008 and went back in 2009 still hasn't wore off yet for me. I don't flip out like every other awful phily fan just because of one down year. God, I hate sports fans, I really do. Especially Philly and NY ones.

Got the replacement block and the bad block at the machine shop. They are honing it with arp head studs in place and I gave them specs this time.

.023" top ring
.027" 2nd ring

.005" piston to wall clearance.

I came up with these clearances with boost in mind.


I hope it doesn't get screwed up again . Ironically, I purchased the replacement block from a guy who also used this machine shop and his motor is going strong.

Dropped the original block off the 23rd and no phone call yet. This is looking promising.

Stopped over there today.

The block is prepped and ready to be assembled, just waiting on rings and a line bore for the main studs I am putting in now.

The culprit of the scored cylinder walls was from the oil rings shattering. I guess there wasn't enough gap and they butted together. The weird thing is Wiseco says right in their documentation that you don't have to gap the oil rings, you can just put them in. Maybe it is not the machine shops fault after all?

If that's what Wiseco says, then per their rules, the rings were faulty.

http://www.wiseco.com/PDFs/Manuals/RingEndGap.pdf

"The oil rails may be installed without modifying the end gap. The gap should be a
minimum of .010”."


Now I feel lucky I chose the shop that I chose, sounds like it may be a Wiseco issue now.

Kind of a catch-22 there. You want to trust the manufacturer's instructions, but experience dictates that you should never trust the manufacturer's instructions.

However, I agree that if Wiseco states that the rings do not need to be gapped and to just slap 'em on and go, and this whole mess is a result of a faulty ring, then I would be calling Wiseco and letting them know what they owe you.

Well, the shop is already doing the work again on their dime, so looks like I can avoid that would-be-mess.

Agree on the catch-22...the shopowner admitted he didn't check the oil ring gap based on that documentation. But we are definitely checking it this time and adding a bit more to it, like .015.

How far are you from Quakertown?

I live up by that area and work at the Lehigh Valley Mall. I can always stop by and give a hand after work.

About an hour. I appreciate the offer though . I am really only working on it on weekends anyway. I refuse to get under the car in the dark outside and alone when it is 29 degrees. I don't mind working in the engine bay in the dark though. So the plan is to get the tranny and motor back up into the car next weekend. Then I can work on the accessories after work during the week with my spotlight. This thing should be running again before XMAS. All I want for XMAS is some smurfing luck with this build. Is that too much to ask????
