Hi,
Lots of progress. Fixed a flaky vacuum connection under the plenum. It was the ported vac signal from the TB extension to the evap vacuum circuit. There was a hairline crack right at the entrance to the rubber connector. Looked OK but wasn't (second one of those I found, the other leak, of that nature, was at the secondary vacuum pump connection.
The new oil pressure switch and FH gasket will be here today and the replacement of the filter housing should go smooth. I did have to drain the coolant down to the level of the lower water pump inlet. The lower hose was in the way of getting the bottom bolt for the FH. I am sure that the hose, being a Samco, could be compressed but I just did not want to mess with it so I drained the coolant.
A special thanks to Dynomite for his heads up on the OPRV cover. The bolts were loose. Blue loctite and torque and I am good to go. Thanks Cliff.
An Aside here with respect the the plastic lines. We all know they age and some age faster then others. I have found that I needed to spend time with a vacuum pump and small stoppers to find all the bad lines. I flex every joint under vacuum and watch the vac gauge. I found that you can't just look at the line and spot the hairline cracks.
If, during the reassembly, I find anything worthy of passing on, I will add it to this thread.
Cheers
Don
