So, back to working on the car now.
Finally put the GT6 in the back shed so I have some space in the garage to work this week. Now time to get that damn crank bolt off the M42 so I can do the timing stuff.
Figured out the way to do it solo without taking the engine off the stand or having anyone to counterbalance:
1. took off the lower oil pan
2. rotated engine upside-down
3. cut a couple 2x4 pieces to use to block the crank from turning, internally.
4. used a 100lb heavy-ass broken floor jack to counterbalance the engine stand since it was tipping over with all the torque I was putting on the bolt.
5. use a 1/2" breaker bar (hoping it woudn't shear off since I don't have a 3/4" here) with a cheater pipe.
In the end it worked!
like so:
so with that off, pulled the timing cover. You may recall I already knew the main cam sprockets were pretty bad and already got a pair of good-condition ones. Now to see what the lower components look like.
The lower crank sprocket is clearly worn and will need to be replaced. The guide sprocket is fine.
unfortunately, this M42 has the old-style chain guide which makes me nervous, so I'll see if I can find a good-condition new-style guide for peace of mind.
Here's something that I'm a bit worried about is the seal below the thermostat. Internally it looks fine and seals all the way around
but on the outside it seems to have stretched out or pulled out. Trying to decide if I should replace this - looks like I would have to pull the head to do so, which is really not something that I planned to do (or want to do)
parts!

that crank sprocket looks normal actually. I have never seen one that isnt pointed like that. From what I know about this engine the crank sprocket teeth are pointed from the factory unlike the cam sprocket teeth.
also, if you like, you can ditch that crank sprocket guide piece that sits right underneath it. its pretty much pointless.
m42 is lookin good. :up:
edit:
I know Ive said this before and people have shit on me cause "its not to spec" but that crank pulley bolt does not need to be so tight. Its stupid to have it that tight. Throw a little loctite on the threads after you clean it up and give it 100 lb ft torque.
It wont come off. trust me.
Youll thank yourself if you have to take it off again later down the road.

Ok, so here we go. After opening up the timing chain case I decided what the hell, let's just do a full refresh now while I'm in here....
So off comes the head!
Now let's look at some points of interest:
Valves....pretty gross
now cleaned up somewhat
cylinder heads were even worse. Took me a couple hours of scrubbing and cleaning to get them nice.
Cylinders look pretty good though.
after
now to look at the infamous M42 timing case issues:
profile gasket is definitely getting some coolant back behind it.
and coolant passageway pretty gnarly as well
but unlike others I've seen, it's not a bad casting or eaten away much, so that's good
on the other side no pitting either
lower timing case needs a good cleaning
staging for more work, gotta order some things
also washed the subie and didn't wash the e30 :)

In other news, I finally tracked down and touched base with Kris Martison, who has been running a 325e in MR out in Nebraska and topping the local class, and ran it in M2 last year at nationals. Apparently there were a few guys in that region running e30s for some time so hopefully will be able to gain some insights that they have learned over the years rallycrossing these things.
And is car is the correct color, lol.
We were all locally talking about how freaking smooth and flat those Nebraska course are - with actual DIRT that isn't red clay. Like night and day from what we run on at Summit.

per Spencer Sheckells, a "broshot" to prove I'm actually doing some work and not just on the internet all night. Yes, in a white t-shirt working in the garage. This won't end well.
