Hi All: I'll be soon rebuilding the cylinder head in my 1974 Duster slant six engine. The head is the stock, correct head with no modifications. I will at that time be replacing the two coolant fittings in the head: The first is the 1/2" fitting screwed into the top of the head that goes to the...
Yeah, it's pretty bad. You saw the photos of the leak down test on the actual gauges. And yes, the testing was done correctly by a very experienced shop that builds racing engines.
Yeah, rebuilding the spare engine, then installing it when finished is looking like the best option right now. Yes, the valves were closed with the piston at TDC when the checks were made. Air was escaping around the pistons into the block.
Yeah, I was pretty amazed when I saw the leak down results. Remember, this is not the original engine from the factory. It is a parts store engine installed in 1988 at a repair shop in Portland OR. That's all I know about it. I can't attest to the quality of the rebuild job prior to putting it...
Okay guys. As promised, here's the data on my sick engine. The first six photos are the results of the leak down test on cylinders one through six. As you can see, several of the cylinders are way down from the 100 psi that was pumped in initially. The final photo is the compression values from...
MoBros and MoSis':
I just got back from a visit to my very favorite junkyard in Wilmar MN where I scored some nice vintage parts for my patina slant six engine that I'm building. I was fortunate enough to run across a few project cars which you might be interested in and wanted to pass along my...
Not yet, but I think I'm narrowing it down to an exhaust leak and perhaps an exhaust valve problem. My buddy is going to contact me in the next week or so and we'll do a compression and leak down test at his very well equipped garage. Again, thanks everyone for the excellent suggestions. Once I...
It has power brakes. The master cylinder is a new aluminum one from Dr. Diff and works great. The vacuum booster was rebuilt and seems to work perfectly. All vacuum hoses are new.
Thanks, Rusty. When you install the Reflex gaskets (both the intake/exhaust manifold gasket, and the one under the carb) on a slant six, do you put them in dry or do you use any gasket cement on them? If so, what do you use? Thanks.
