    Hi all, I recently found out during an engine rebuild that my connecting rods had knackered the block, so instead of rebuilding the engine, I now need either a replacement to rebuild or just a block itself. It's a type 4 engine to go in my '79 Bay window with a CJ engine code Any help would...

    Hi, I've bought myself a T25 with a dead engine. It's a 2.0l Aircooled CU unit with Hydraulic followers and a single Weber with electric fuel pump. I have stripped the engine and split the case and found the cam is pretty well worn as shown below! The cam bearings were also cream crackered...

    I am currently running a 1300 sp (af code) engine in my 69 beetle that puts out about 40 bhp. I am thinking of an engine upgrade and was wondering if I could use this engine as a base? Is it possible to upgrade it to say a 1664 and fitting ported heads, ratio rockers, balanced crank and...

    I bought a crankshaft from someone off here and I think it may have been reground but I'm not sure and the seller is not sure. What are the standard sizes of the main bearings? and Big ends?

    I've searched and found a couple of threads that say where to remove material from but..... I've got 10grams between lightest and heaviest. Is there any point in me trying to get these matched as others are talking about 3g being a lot of difference! Thanks :)

    Measured the CC of my heads and they came out at 50cc, but should I measure with the disc inside the step in the head or on top of it? I made my own disc so made it to be a tight fit inside the head. I'm thinking maybe I should measure not including the step and then add the step onto my deck...

    Does anyone know what relief valve I should be using and what length the spring should be? It seems OK but I'd like to double check :) Ta

    At the end of the summer I'm planning on rebuilding my engine and making a 'proper' job of it this time. I'm basically going to pull it apart, get the bottom end balanced, put it back together and set the CR. I noticed the other day that I've got a bit of endfloat. Obviously running around...

    I've stripped the heads off my engine and there was a bit of oil sitting in the bottom of the barrels, not loads, but some. Is this a bad thing, do I need new piston rings and or a new oil ring on the pistons? The rings look fine and are not broken or look damaged. Thanks

    Alright guys Just a quick question really, how do you match the Dizzy drive up with the crank. Needed to take it out as ive fitted a cam. Im guessing theres a way of doing it so the dizzy matches the spark pattern or do i just slide it in.

    Thinking about building a stroked 1300, so 77(bore) x 76(stroke), this would give 1416 CC's. Or would I be better off stroking a 1600, so 85.5(bore) x 76(stroke)? Everything I have been told is that a 'Square' engine has very nice characteristics for daily driving, lots of torque and a very...

    An American company has managed to acquire a large quantity of genuine VW Type 1 crankcases. The problem is that these cases are specifically for the local Brazil Type 2 model, are single relief, have very small oil galleries and a tiny oil pick-up tube. They are being passed off as late style...
