Ya know, I'm no engineer, and I'm sure there is a real good explanation and reason behind the whole stretch bolt thing, but who needs problems at this point. Sheesh! managed to get this guy out at least! This is a rocker tower bolt.

As you get into one of these motors, you discover just ho well they are put together. There was some wear on the valves and guides, but everything else was in good condition. When I felt the slop on the valve guides I panicked, but replacement is as easy as driving them out and driving the new ones in. I measured the existing guide height with a depth micrometer and carefully drove the new ones to the correct height. I can't show the pictures of the new guides because they are apparently unacceptable, but here is the engine in the stand!
here are some pictures i tried to load before

I've been putting the engine back together, now that it isn't such a greaseball, and everything looks pretty good as far as timing goes. My question to anyone out there is this: I've got the crank pointing TDC, and the timing marks on the cam are pretty much lined up, how do I know if the IP is in time? How do I know I'm not 180 out of time? I'll be posting pictures later today. Any input would be appreciated.

if you take your pics and reduce the quality the size will make the site happy and you will not sacrifice the size, you can use photo shop to do it pretty easy. Hurry up and finish up i have a 81 i am going to be doing.

Discovered that a good scrub in a tub with diesel fuel for solvent, followed by a water rinse, followed by a quick spray with brake cleaner would yield some pretty good results. Any stuff left baked on came off pretty well with the help of a HF soda blaster. It did a pretty damn good job! Pictures to follow.
trying this picture thing again!

I've been effing around with these photos for way to long trying to get them to load on the reply, or show up in my email. I'm loading all photos onto photobucket and try to link it up. I'm going to have to get some one a lot more tech savy to help me with this part.

That being said,here is a rundown of what I would like for my thread to chronicle. First off, I don't have a big shop and lots of room. My shop is my garage and driveway. I do have a fair amount of hand tools, a compressor and some air tools, cordless drill and impact driver, a tiny drill press, sawsall, 4 inch grinder, and a Ready Welder. The point here is if you are thinking you need a big shop and every tool under the sun, well you don't. Sure they are nice, but you don't have to have it all to do one of these projects.

The first thing I discovered was that cleaning an old diesel engine is dirty work. I went through a few cans of brake cleaner before I discovered that diesel fuel is an excellent solvent. I went to Home Depot and picked up a concrete/mortar mixing tub and used that as my solvent tank. along with the tub, get a variety of different shapes and sizes of scrub brushes. You throw the dirty part in the tub, give it a scrub, rinse it with water, then give it a quick spray with brake cleaner. comes out pretty clean. I did buy myself a Harbor Freight soda blaster and it really did a good job on the real stubborn stuff. So, clean parts that needed it got a coat of paint, and the aluminum stuff is staying raw. I may powder coat the valve cover at a later date.

In the earlier post I showed the cylinder head off the engine and kind of chronicled that chore. Heavy dude! While I was that deep into the engine, I gave everything a good look. I pulled the upper half of the oil pan and checked the main bearings, and they were in excellent condition! I cleaned out the oil pump and replaced it's chain guide and replaced the rear main seal, then put er' back together. Anaerobic gasket maker used here. I repainted the front pulleys and the harmonic balancer a nice gray color. I then took a black Sharpie and redefined the timing marks. I put a light coat of copper coat on the head gasket and put the head back on. This engine uses stretch bolts. Yeah, good old stretch bolts. This means one time use only. So , be prepared to drop some dough on new head bolts if you do this job. I did not replace the rocker tower bolts and managed to break one. Really happy about that! Fortunately there was enough sticking out to get my stud remover on it and crank it out.
