Re: [MBZ] My afternoon working on MB's
IIRC, you torque to given value - not all the great, then turn the bolt 90 degrees, let it sit for 15 minutes, then turn it another 90 degrees. These are strech bolts. You need to measure the shank of the old ones before re-using them to see if they're in tolerance or not. I just bought new bolts from Rusty.

Re: [MBZ] My afternoon working on MB's
My experience is that acetone does not mix with Mobil 1 ATF - I just shake it got get the globs as small as possible, then squirt on liberally. I only mix what I need for the job at hand, and use it all.

[MBZ] My afternoon working on MB's
Spent the afternoon working on my '95 E300 for a bit (fixed the other rear window using the 210 slider previously discussed) and then I dove into removing the head on my '87. I soaked the exhaust nuts/bolts again (had soaked them all with PB Blaster a week or so ago) prior to starting on the '95 window, and when I returned they came off like butter. PB Blaster is really nice stuff, when you can give it time to work. So, exhaust came off, pulled turbo drain tube, finally wiggled the turbo supply oil line out of the block. It is time to loosen the head bolts! I'd ordered the Hazet bit from Rusty for the head bolts (triple square 10mm), and it was really nice to have. Didn't need it for all the bolts, but for the seven buried under the cam bearings it was very nice. Those head bolts are TIGHT! Needed the breaker bar to get them all loose. Interestingly, one bolt each at #1 and #6 cylinders was dry, the rest were well oiled. I thought all of them were supposed to be oiled prior to installation? All came out without drama. Time to lift the head off! Realized I needed to take loose the ATF dip stick tube, and the exhaust fought me some more, but I finally had it lifted free. The replacement fire log for the original cat was a tight fit, and the turbo support wanted to hang up in a coolant line, but I got it out. Tore up the fiberglass insulation pretty good, need to address that. I'm a total novice, this is my first head removal, so I may not be able to read the signs, but the head gasket looks just fine to me. No evidence of coolant or oil blow out anywhere. However, there is cracking between every single intake and exhaust valve seat. #6 is the worst, followed by #4. Upper chain guide needs to be replaced - small hole in it, and worn. How hard to do the tensioner chain guide while I'm this far into it? My new head is still at the shop, but probably ready to be picked up, so maybe I'll have some time in a few weeks to start putting it all back together.
