Well, I finally pulled the heads off of the first motor (the original, the DDEC) after much struggle. All of the hoses had been rusted miserably together to form unbreakable bonds. A day of soaking in PB Blaster and I managed to break a few free, and only damaging one, which thankfully I have a backup for on the other motor. Whew.
After detaching the electrical injectors, breaking all of the enormous head bolts free and labeling everything obsessively, I ended up asking for a hand from a strong friend to muscle them onto a wheelie cart for me, then into (and back out of,) the washing machine.
Mmmm... Downy fresh heads!!
After they were clean, I learned how to Vacuum Test the heads. 3 out of the 4 cylinders held vacuum, which means that the cylinder that doesn't... needs a valve job! Augh. Well, not too bad, because I've been interested in learning how to do one of those. The problem is now to figure out: do the one bad one, or do them all? If one is bad... then are the others going? Or is this just the case of damage from my internal issue, and all of the damage that will be done, has been done?
But cost, too. I am dead broke. I could do the one cylinder, and it would save me in time and money... and the others ARE fine.
Oooohhhhh the decisions! DECISIONS! Input, anyone??
Here, I will include some more pictures of my motor for fun!!
(note: objects in pictures are larger than they appear!)
The heads, freshly removed from the block.
Thank goodness to rebuilding the VW engine first! Priceless things that you learn: LABEL EVERYTHING!!! No, don't even THINK about it, there is NO WAYYYYY that you will remember where that bolt goes in a month from now, I don't care how obvious it looks today!!! Label it!
I guess now you could say I am a bit obsessive about the labeling... BUT it will save my butt when I go to put the thing back together. I also stamped into the heads "R" and "L" and the numbers of the cylinders so that the labels on the injectors make sense. *sigh* I am such an overachiever...
HERE! Thoroughly cleaned heads, ready for the next step.
OH! And as promised, here is a neat picture of the intake.
Yes! That's right! The intakes are on the bottom of the cylinders. Tell me that's not awesome! Silly 2-strokes...
I love old things and outdated technology!
Now, speaking of, perhaps its time to go write some letters on my typewriter...
