951 Turbo Replacement and Engine Mounts

Been tinkering on this 86 951 that is in dire need of a new turbo and engine mounts. If I recall correctly, the owner found an old socket in the intake boot which chewed the turbo fins down to a pulp. Not good. So with a rebuilt turbo in hand and a set of engine mounts, it was time to tackle it.

Covers on and ready to go to work.

First thing to do was to pull the intake off so we can somewhat see the turbo.

After a few minutes of work, I looked down to find a coolant leak along with a power steering leak. Turns out the hose clamp on the lower radiator hose was broken, so I installed a new one. Hopefully that was it.

It is a big, oily mess and really hard to see where any of the leaks are coming from, lol. This engine needs a complete reseal, but that will have to wait.

Here you can see the old turbo fins ground to a pulp. Hard to push any air without any fins!

Underneath the turbo, oil was puking everywhere. Partially due to the fact that it was missing one of the turbo mount bolts to seal the bottom of the turbo to the oil return port.

After some cussing with the rusty fasteners, the turbo is off. Someone had been in here before due to some missing hardware here and there, and I believe it was probably to reseal the oil air separator.

Good ridance.

After the turbo was out and some holes plugged up I was able to at least clean up the area a little bit. I killed a lot of brain cells in the process. Winter work in the garage sucks with the door closed.

And the rebuilt turbo ready to go on. I need to pick up the hardware to swap on the downpipe, then it will be ready to go.

With the turbo out of the way it was time to tackle the engine mounts…..remember what I said about things happening together? LOL. The mounts were completely collapsed, and were not original mounts. My guess is all the oil puking on the rubber helped to do them in. Again, I can easily stick my finger in between the crossmember and the top of the engine mount.

With the engine supported, I was able to start dropping the crossmember down and at the same time lifting the engine for clearance.

And the new mounts in. This has turned out to be a really messy project with all the oil on the bottom of the engine. Hopefully I can get it cleaned up a little in the next few days so we can track down the biggest oil leaks and get them stopped.

The previous owner called – he wants his 10mm socket back. 🙂

That looks like a lot of work ahead. Good luck!!
