Follow me along as I venture into type 4 hell as a newbie to VW's!
This thread will show how a V8 guy does a 4 cylinder (IMG:style_emoticons/default/laugh.gif) Okay guys, pulled the engine out last weekend, and today project was disassembling it. I knew it had a knock, and it was super oily, but found out that it had gotten worse that I thought, and had actualy spun a bearing, with another connecting rod getting close to it. Damage report: -The crank is a little tweeked, and should be able to be ground to get rid of any evidence of the connecting rod slamming down upon the journal. -1 cylinder has been scored terribly with 1-2 mm scratches in it. I'm hoping that the KB oversized pistons are big enough to compensate for the scoring to be taken out (IMG:style_emoticons/default/confused24.gif) -lots of tiny bits of bearing EVERYWHERE! The good: -valve train is in good condition -cases have NO marring on them -cam looks good -connecting rods are perfect Other than that, it's just goint to be money to get new parts and take the crank in to be ground and possibly rebalanced and tweeked back to alignment. And now for some pictures.......

Okay guys.....everything is entirely apart in the engine.
I'll try to keep working this weekend even without any parts. Then again, the engine bay needs to be cleaned.... So, I know I'm beating the dead donkey with this question, but can the camshaft be reused at all, even with new lifters? I'm in awe that a newer camshaft (Sneider I h=think you said?) would fatigue so terribly that it couldn't be reused...I just don't get that. Yes, I need a new crank, yes I need new cylinders and pistons, and yes I need to rebuild the heads.....but the cam seems like it's fine. I plan on taking it to the VW performance shop 10 minutes away and see what they think. Work will continue this weekend, but just thought I'd put this out there. |

I plan on taking it to the VW performance shop 10 minutes away and see what they think. Work will continue this weekend, but just thought I'd put this out there. It's not fatigue, it's wear. The cam lobes and lifters will develop a wear pattern, and if you swap the lifters around, you're rolling the dice as to whether the wear patterns will be compatible or destructive. I would think that with a new set of lifters, you'd be okay, but... ...an aftermarket cam is one of the big steps that you can take to increase performance. If money is tight, shop around. I got an unused Web #163 for $72. |
