AMS 2.0 build/ FP beehive, kelford 272 problem
Some updates.
Over the past few weeks I have been noticing some oil consumption and a little blue smoke. I decided with my "need" to make more power and the fact I was well into the 70k mile range on the stock engine it was time for a little added protection.
On to the good stuff.
I found out my maf was just about to give out on me, good thing I caught #1
This is what I found when I pulled my igniton off, "lake evo"
I had signs of water in the tb and the piping. I can only guess that all the water is from the monsoon we had after pinks and all the large rivers running across the road on the SS.
Just one pic of the leaking valve seals.
Well at least it was still together, some wear but I didn't think it looked abnormal.
Found out why my valve seals were leaking!!
Now onto the new parts.
Other than my missing rear main seal bolts everything came back to me. No biggie they are just 10mm.
Note the block said evo 9, here is what it takes to run a 9 block in an 8
Thanks to Aaron for helping me get this beast on the stand.
Machined balance shaft.
Well, thats all I have until I get the head back.
UPDATE:
Well I talked to T.H.E today about the head. To me it sounds as though I am very lucky to have taken it apart when I did. In addition to the vavle seals being destroyed he found several other possible issues.
The guides are badly worn and in need of replacement.
Another interesting thing he found and is assuming what led to the valve seal destruction is a possibility of coil bind.
He Did a test and only had a max of 10 thousands of an inch between the coils. Tomorrow Im going to call FP and get the specs on thier beehives to verify I didn't just get a bad batch.
The bottom of the retainers were polished from the contact with the valve seals and noted when replacing the guides he will drop them down 50 thousandths and that should solve the clearance issues in the future.
Im wondering what route I should go with on the spring issue. If the springs are up to spec, is 10 thousandths considered a safe amount of coil clearance at max lift to prevent coil bind in case of an over rev?
I have on occasion ran it to about 8k with the new springs and cams. Is this considered too high or this combo? Kelford 272/fp beehive with stock retainers. evo8

I think its fairly common for people to use some kind of aftermarket valve seal, especially with dual springs. They aftermarket seals are slimmer and stand less chance of a close spring pulling it up off the guide. For reference my engine had 64k and had 3 bad valve seals, i found the remains of them in the same spot you did.

I don't have dual springs. I have FP beehive spring which retains the same clearance around the seal and allows the use of the stock retainer. The valve seal ended up being bad due to the cracked valve guides and excessive valve movement. I know of the need for an aftermarket seal with dual springs and thats why I did not go with them, and because most of the ones on the market don't do as good of a job as the FP.
As for the build I finished it July 4th weekend. I have since changed to SD,e85 and trapped 136mph. I have since sold the 35r and gone with a bigger turbo and some new parts to get my et's down.

Where and what exactly is that where all of the springs were caught?
