I bought a block from a 88 Porsche turbo s. The block didnt come with the oil cooler. So im replacing the oil cooler with the one off my car and that was a 87 turbo. the problem is that the blot hat sticks out of the oil cooler with the O ring does no slid into the new block. Any imput?

Do i need to source a bolt from a turbo S?







thats as far as it goes in :/

Hammer time!

Does it appear that there's a sleave on the block that makes the hole smaller? Last, how certain are you that this is a S block? If no sleave and it's def. an S block then allignment may be your issue.

hey sorry I missed your aim the other day. I left it on and by the time I got back you had already signed offline.

That looks like the updated oil pressure relief valve... very good. One less thing to worry about.
Loosen the housing bolts and reinstall the OPR.

there's a sleeve in the block. it does make the whole smaller. I havent tryed too remove the sleeve yet

What are the block stampings on the drivers side of the motor near the flywheel end. Also, the oil cooler is loose from the block still correct?

no i bolted on the oil cooler too the block and pulled the bolt from it so i could aline it without the huge oil cooler on there. didnt work though :/

M44.51 is a non turbo S block. Are you sure the 6 isn't a G. If I am remembering correctly, 1986 is a G code, H is a 1987 and so on. Usually the engine serial starts with 45, then a letter indicating the year, then the rest of the number. Sounds like you might have a 1986 turbo block, in which case you need to use the earlier style OPRV.

PorscheDoc

I just check a spare 86 turbo block I am building the the garage. Code M44.51, and the 3rd digit is a G.

VOoDOoGTX

yeah i verified the numbers there correct. ok so the guy lied too me about it being a S. that dosent really mater though.

PorscheDoc

Nah, you just need to find an early style valve now. Did you have the balance shafts apart? If you are building the motor from scratch, make sure you used the 1986 balance shaft bearings as the covers and bearings changed in 1987. If you didn't touch that part of the motor, or didn't replace the bearings, then disregard.

lindsay racing balance shaft delete so this block is from a None S from what year? i need to order the the baffle kit for the oil pan i was under the assumption it was a S and they addressed that problem a bit beter.

VOoDOoGTX

wait so if this is a early block... why did the balance shaft delete from the late model car work for this one?

PorscheDoc

The 3rd digit in the serial number I am guessing is a G (It should be a letter, not a number), not a 6 if you look close, would would indicate it is a 1986 turbo block. Also, I am guessing there is no auto tensioner for the timing belt on the front side, which would also indicate it is a 1986. That would also explain why there is a sleeve in the block for the OPRV, and why the later style OPRV won't fit.
