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.......

Do your homework.
The biggest mistakes we see come from guys with extensive experience of other engines and trying to apply this experience to the TIV engine. My best advice would be to forget everything you know about V8s except the 4 strokes of the engine as these are the only characteristics they share. ...and I see a crack in one of your heads from here. (seriously) and your thermostat is blown and should be replaced.. Remove those sodium filled exhaust valves and replace them with quality stainless steel items. I haven't seen a "perfect" stock cam come from a TIV engine in the past 15 years.. Post pics of it and DO NOT RE-USE IT! the cam is the second part installed into the engine and the most critical wear item of a TIV engine. If the cam goes south it's the second to last part you'll remove and replace and a full tear down is required. re-using a cam is like a very nasty game of Russian Roulette. Read for at least 3 months before you buy the first part and do your home work, I have to help guys out of situations on a weekly basis because of poor decisions during the component selection processes and many of them spend double what the cost of one of my kits cost and they still don't have matched components. Don't buy a single part until you have measured every single part n that engine and have come up with a map of the project. I don't want to come across as abrasive, I just want to get the point across on this topic... With this engine, trying to save a dollar is the fastest way to spend three.
