I just cut into my upper oil cooler line with the power steering belt due to a broken motor mount on the driver side. Oil went everywhere.

I have it parked right now and am performing A LOT of maintainence.

I decided to do a valve adjustment as it was almost time. I got everything ready and went to turn the power steering belt bolt to get the lobe pointing up. The PS side of the belt was turning but the motor side was just slipping. I tried tightening it. I even took the belt off and cleaned everything. No change. It still slips at the engine.

What am I missing here?

The PS side is spinning the belt so there is nothing going on there.

Here are some things that might be factors...probably not but worth mentioning:

Oil is out as I'm waiting for the cooler lines to get here before I put new oil in.
Left motor mount is cracked.
Compressor belt and compressor are off the vehicle.
I washed and degreased the engine with Simple Green about a week ago.
Belts are not cracked at all.

Hmmmmm....

Thanks!

The best fix is to turn the engine per the FSM ..........using a 27mm socket on the front crank bolt.

I know there are several posts here telling you to use the power steering shaft bolt, but personally I don't think it's a good idea due to the possibility of damage to the power steering pump.

How to turn the engine.

Maybe the engine is locked due to lack of lubrication.

I sometimes just grab the belt and assist it to TDC while wrenching the pulley. Watch those fingers!

I thought about that, but wanted others opinions. I figured it should still turn, but maybe not?

Thanks so much for your help and thorough explanation.

How much oil was lost and for how long did it continue running?

Can you 'bump' it over with the starter?

I agree with SD but want to add that you can always pull the GP's to reduce compression and make it easier to turn over

How can I detail it further than was already done in the previous post by SD Blue?

The only other option is to bump it with the starter.

just pull the injectors and not only will you have the opportunity to clean out the PC's threads, but you can get fresh heat shields in there and take your injectors over to have them pop tested and balanced...
this also makes it REALLY REALLY easy to perform the valve adjustment.
