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.......

Thats more like it, BUT 200 is even steep for a reground crank, unless your core is trashed. Most cranks don't need more than a repolish unless they have seen a bearing failure.

This crank is TOAST I believe. It saw a bearing failure (one bearing went, and another was getting ready to! It was run for that long with a knock), rather severe, and the crank is tweeked (IMG:style_emoticons/default/headbang.gif) . Sadly I don't see how it could be reground back to specs. Man, going over prices and such, and doing more and more homework, I'm starting to hate TIV'S (IMG:style_emoticons/default/laugh.gif) Just kidding...........to a certain extent. Maybe I'll do a Suby or SBC conversion....I'm sure you love me for doing that would you Raby? (IMG:style_emoticons/default/poke.gif) (IMG:style_emoticons/default/happy11.gif) On a more serious note, I may be looking into a -6 conversion. I can get a rather nice 2.0l -6 out of a 911 in return for a SBC 327 from a good friend. In theory I'd be getting this engine for free as the 327 is just sitting and I have no empty engine bays for it......(minus the 914..... (IMG:style_emoticons/default/sawzall-smiley.gif) )I have the plans and drawings to make fibre glass engine tin, and would only really have to fork out $375 for an engine mount and the other sums of $$$ that would go along with getting one hooked up (exhaust, oil and electrical) Any ideas on this type of conversion guys, because I'm honestly scared of rebuilding this 2.0l TIV and spending WAY more money than I initially expected, where I pretty much have a checklist of conversion bits and pieces rather than a list on how to build a working TIV! |

The oil tank for a /6 is $1k. Carbs? Exhaust? Sounds cheap up front, but you'll get in deep quick. Plus, a 2.0 /6 at it's best won't give you much over a good 2056, and it weighs more. I went through the engine decision, and decided on the type 4. Conversions are tempting, and impressive if done well... but they cost $$$ to do well. If your budget is tight, stick with the type 4 rebuild and shop around for parts. Deals are out there if you are patient and persistent. That's what I'm doing. So far, I've spent $258.71 and saved $761.79 over what the parts would have cost from retail sources. If your crank is shot, find a core engine. You can get a 1.7 core for less than $100, and build a nice 1911 out of it with your 2.0 heads. Or, find a 2.0 core... they are out there for $300-$400. |
