I started on the plenum assembly restoration today. I had the 1/2 side sitting in solvent overnight and went to it with brushes and scotch pads. I sat there with the piece sitting in very hot water with Purple Power in it and scrubbed, rinsed, scrubbed, ran brushes through galleries and holes, etc. This is…

Murbella – Day 25 – Cylinder Head Tear Down
I decided to not waste over $580 in buying new FI heads and will replace all the valves, and have the head itself tanked and valve jobbed at a machine shop. If the shop can determine if new valve guides are needed, and they can do FI heads with the odd 9mm larger stem on…

Murbella – Day 25 – Final case washing!
Last of the tapping I started where I left off yesterday and did some final adjustments on a few of the holes I tapped. I’m still not happy with the 3/4 lifter hole that I tapped too deeply. It shouldn’t impact anything, but I’d rather have it closer to the case surface. I tried to…

Murbella – Day 25 – Sorting and some and fan shroud/alternator removal.
So I needed to sort through all my parts again to see what I had so I could trigger orders at AApistons.com and CIP1. I wish I had my new credit car but I wasn’t thinking about getting that 0% interest line of credit prior to this weekend and I had to take advantage of…

Murbella – Day 24 – Drilled and tapped the oil galleries!
To be frank, I probably didn’t need to go this far. However, every time I put a brush or swab down into the oil galleries they continued to come back dirty so I went ahead and pulled only the plugs necessary for oil cleaning, as well as the two other small ones at the rear…

Murbella – Day 24 – Some tin’s degreased.
So I’ve a lot of the tins soaking in solvents the past few days to try and get the oily residue off of them. The heat exchanger tins were exceptionally bad, with layers of oil and dirt on them, and the undersides of the cylinder tins were pretty bad as well. Oh. And the 2…

Murbella – Day 24 – Case Inspection.
The case cleaned up very well. Sure there’s some corrosion of the allow, especially at the bottom heat tin mounts, but I’ve seen that on every original engine I’ve ever disassembled. The mating surfaces of the case halves feel smooth. The bearing saddles feel smooth and I detect nothing that would indicate the crank was…

Murbella – Day 24 – Case cleaning and crack detection
With the case dried, it is very easy to work worth. I focused on mating surfaces, using mineral spirits and a basic dish washing scotch pad. The yellowish color that looked like stains here in there were the remnants of the previous sealant. I was able to scrub up most of this, and then went…

Murbella – Day 24 – Case Power Wash Time!
There’s noting I dislike more than having to deal with a filthy oily and dirty engine case when I’m disassembling it. Of course, it is kind of unavoidable for an engine that has been in a car for decades, and even worse for those I’ve bought that were used in sand rails and such. After…

Murbella – Day 24 – Final Disassembly
So I got outside completely forgetting that I had not done everything needed to just grab them for power washing. It took almost an house to get the remaining cylinder studs out. There were about 6 that was fused to the case. I used up my one remaining cylinder of propane heating up the studs…
