That's just my aspie sensibilities. And it's kinda funny that I didn't realize that at first. What he was saying was basically "a good way to damage the engine is by running it."
You're not too far up the aspie curve. I've known a few as there are a lot of people on the "spectrum" up here. It really pisses me off that people pass autism off as some random occurrence and won't even consider that all the vaccines and drugs we pump into our kids when they are young MIGHT actually be causing a lot of it.
So take the carb and battery off, put a bag around the distributor, and pressure wash it. I'm immensely happy about not having to deal with sensors and sensitive electronics on this old engine. Should I cover the starter too?
You can just take the air cleaner off and put a bag over the carb or stuff rags down the throat, or both. Just trying to keep water out of the engine and ignition.
If we were going to drop the engine out anyway, how much extra time would it take to replace the clutch, do a ring job, replace any burnt valves and check clearances? Maybe even polish the crank, but I don't know how involved any of this is. My guess is that with 112k the cylinders only need to be honed and it doesn't need professional machining, right?
While sending the engine off to a machine shop and having it rebuilt would be great peace of mind, I've read around and it seems the turnaround would be months, and I called a shop today and they quoted me a range of $1300-2600 which is pretty 'ouch' compared to the cost of rings, a couple of valves, gasket set etc, plus some good food, good scotch and labor But then, I don't know if that's something that can be banged out in an afternoon, or if it's such a meticulous process that it would take a week to do. I watched a machinist do his thing on youtube last night and saw him play with 0.1mm clearances on thrust washers. That was a racing engine though, for a car probably designed to hit >150mph.
Lol. You are ambitious! My body is aching thinking about pulling a motor. Anyway, once the engine is out, which can take all day, the clutch is easy and takes about 15 minutes. Rings are a bit more involved with pulling the caps off the rods and protecting the crank journals. If we get some bearing measurements, we can decide what to do with them. Chances are if the oil pressure is good, the crank is probably fine. I usually have a shop do the valves. I'm too impatient to regrind and lap the valves. While the head is at the shop, we can have it checked to make sure it isn't cracked or warped. I do have an engine stand, so working on it is easy once it is out and on the stand.
My biggest fear pulling a motor is taking the exhaust off, which can/will break a stud off in the head and I suck at drilling and taping out broken studs.
So with an engine pull, I would plan on at least three days, One to pull it, one to fix it, one to put it back, and may be a forth day to drink until we forget about how much the body aches.
Wow, so I guess, like everything else I've discovered about engines, it's much more complicated than it appears. That diagram is completely different from my manual, which shows detonation as that corroded white ashy look, but, obviously, I definitely trust you.
Hopefully they won't come out so lean after I fix the vacuum leaks & HAC lean mixture/timing advance.
I'm just going to rip the plugs back out and fix the gap, then chase them and pray they don't need to be coiled yet. Not gapping them was probably the dumbest mistake I've made in a while. I was also putting off the compression and leakdown test until after I replaced everything, then failed to realize that would be hard to do with damaged threads. So I'll do that then too.
I'll update tomorrow after I get all the work done! I'm very excited about it.
Engines are not all that complicated, there's just a lot of parts to it and it can be overwhelming at first. I learned by just doing one thing at a time and taking my time. It helped that my dad was into doing his own mechanic work and did an engine swap in a 74 Toyota Land Cruiser which I "helped" him with.
A few years ago, I was able to do a body off redneck restore of a 1-ton Dodge diesel which was really cool, but I still hate body work with a passion. Finding non-textured, colored bed liner was a good thing.
When you are chasing the threads on the head make sure it is stone cold and you find good threads to start on. I have fucked up my share of spark plugs holes by cross threading plugs into them. Tends to make the spark plugs jump out of the motor when you are cruising down the highway and that's a real bitch.
As far as VW's, I've had a few bugs, a transporter van, Eurovan (my favorite), and currently, we have a diesel Jetta station wagon my wife drives.
Good food is always great, even if it's just burgers on the grill!
