I hate this $&@"%#^ car
My OPRV sheared off while trying to remove it. I have the head, some of te threads, and the spring.
So two weeks ago I had a car that ran with a little coolant smell in the exhaust. Now I'm $2200 poorer and have a car that doesn't run at all. |

Steve,
Sorry to hear about the frustration. Your 1986 944 should have the "one piece" valve. Can you add a picture of the parts that came out? The "one piece" valve does separate to get to the intermal "O" ring to replace The bottom half may be stuck in the hole. In any case, you need to remove the oil cooler housing if you cannot get to the stuck piece. Here are the instructions to replace the 2 "O" rings and it may help visualize the piece inside the block.   GL John_AZ |

I'm on the iPhone but it looks like mine sheared at the threads in part #1 as mine is much shorter than the picture depicts.

This is what the early "3 Piece" oprv looks like (by djolin)  Does your spring look like this one? GL John_AZ |

Nope. It's a one piece. I just got it out of the housing. It sheared in the middle of the threads. More alarming is the housing. There are spots where the threads are broken off. Not crossthreaded, not galled, but snapped off. I've got photos I'll upload later.

You should be able to find a used OPRV assembly for about a hundred bucks. Why are you in the hole $2200? That seems simply astonishing for this particular job. It's not all that hard.

Wow, the housing is f***ed. Not sure if you can get a thread chaser that big.
Evidently, the housing is not lined up with the block when your mechanic probably forced the OPRV with a ratchet and socket. It should thread in easily by hand and tightened with a wrench later. The OPRV threaded section is thin walled and can break where the o-ring sits on a groove inside the threaded piece and the bore is tapered to allow it to go in easy but not easy to pull out. You may need a new oil cooler housing and OPRV. Call Georgeb, he may have one set on the shelf. You are already out by $2200 so another maybe $200 will be change. Good luck!

Heli coil insert if you can Drill and find right size. Probably on line since it's metric! A woodbee machineist kid would probably do for 50-70$ if you get the right size drill bit and Heli coil. Try to find a local kid that can come by after his normal machine/auto job and make some extra cash.

check your PM's. Now that it's a more civilized hour and I'm thinking clearly again, it should be easy to find a new oil cooler housing if you would rather not mess with replacing the threads. The problem with replacing the threads is, since the OPRV depends on such an exact fit, the threads will have to be exactly straight and centered. For some reason I was thinking the threads were in the block.

Idiots and tools should never mix. Still, getting a helicoil in that should be a relatively easy/simple matter - probably need to call a few places to find one that has the correct one for that size/thread pitch though.
