Engine block leak down test

[Trey T]

What heat exchanger - radiator, engine oil cooler, or tranny oil cooler?

How did you come up with the number, percent coolant intrusion vs bearing wear percentage?

Good thing you are changing the IMSB, as 1% of coolant intrusion into the IMSB equates to an increase in bearing wear of 83%. Lots of people don't realize this and then after an intermix experience they lose an IMSB shortly thereafter.

Thanks, I had the oil cooler pressure tested and it showed tight (according to my mechanic). Had the seals replaced anyway. Found out a few hours ago one of the head gaskets is blown in several places. Should know by Tuesday if either of the heads are cracked. Please say a little prayer for my Boxster, feel like its on life support.

Directly from our bearing Engineer and the manufacturers of the bearings as well.

Update, one of 2 heads confirmed cracked. Gaskets blown as well. Any suggestions as to where I can find a cylinder head for a 2001 S? Also looks like the clutch flywheel is thrashed. Will likely overhaul transmission as well. I'm in a fetal position. Kids' college education vs Porsche.

Dave where in SoCA are you? & what shop has your car?

Do a Google search on "rebuilt Boxster cylinder heads" - you will get many options. rebuilt for my 2003 was just shy of $2000. Make sure you get the right part!
