Bend pushrod on #4 intake

[wrenchnride247]

Oh yeah. Forgot to ask about that engine case. It looks like a industrial engine case(don't remember the case code)that was used for non motor vehicle application's (running generators, compressors, and machinery If I remember right). I'm sorry I keep telling you bad news . It's not on purpose at all. Just trying to help.

Piston/head #3&4 revisited:

After some wire wool this is how the pistons look like after cleaning up:





On both pics you can see where the intake valve nicked the piston head, but is very clear in the second pic. No doubt that the deck high is way off. The "pro" that did the fly cutting on the heads cut them too deep...

Yikes! I am sure I put the rings on the right way..., or did I? Well, I will be pulling the sleeves off at some point now too! As to the case, I will verify the code tomorrow. This should be a stock Vanagon case. I did not mention it the first time round I think.

I remember about twenty years ago seeing a typeI style case with a oil filter on the block, and was told it was a "industrial case". I have not looked at a vanagon case though.

If you get your heads machined to the same depth, you should be able to adjust your deck height with cylinder shims, and your head chambers with copper gaskets to get a good compression ratio.

Are you that old!!?




As a matter of fact, I have got 2 of those engines here too. I did not notice though if they had the oil filters.

It is good news to know that the head might still be saved. Problem now is to find who can do them. Anyone know where the fly cutting tool can be bought?

Well, since i'm the only one replying to this thread... Gene Berg makes one that fits in a Mill, or drill press, and has good instructions too. I got one... wait for it... about eighteen years ago . I think it was about $60 US back then.

Did you get your PM?

Sorry to jump in here - I can't add anything new to the problems you are having, but can tell you a bit about the crankcase!

That is not an industrial engine crankcase - it is a Vanagon / T25 "CT" or "CZ" case - 1600 / 50hp aircooled from 05/79-12/82. Cooling fan was on the end of the crankshaft like a type3. Originally had hydraulic cam followers same as the 2.0 CU & waterboxers. If yours is now solid lifters then you will have had to use 2.0 CJ ones or bush the case & fit stock T1 lifters. It used Waterboxer pushrod tubes. Other features of the block are that it has the oil cooler mount closer to the distributor. Cooler lies flat like a type3 but on top of a large ally spacer block.

This engine was generally not reliable as it had marginal cooling in a heavy vehicle, so suffered from overheating, but it was a useful development that led to the waterboxer engine. It is an OK engine if you sort the cooling out, but not one i would do as a performance unit with original CT cooling.

Not many sold in USA - most sold in Europe and then it was only the bottom of the range - most went for the 2.0 CU engine.

wrenchnride247,

yeah, got the PM. Trying to mock-up a 'system' to use a dial caliper to measure the valve lift. But I am stuck at the moment, because I cant seem to source a dial caliper anywhere(fast)!!! And a magnetic base support arm, almost impossible to find here. As rare as rocking horse droppings!! Visited 15.....yes count 'em... 15 shops on Friday with no luck. One said that it is not available at teh moment, and MIGHT be available in two weeks time, no gaurantee. And eBay France is of no help either So the heads are not making as much progress as I want

18 years, good lord! will this be what you are referring to?


Moog,

Thanks for pitching in. Indeed it is a CT case. I am sure that it is 2.0 CU lifters as we have not machined anything other than the cyl. sizes on the case. I will be looking into an alternative oil cooler with forced air to try and aid the cooling issues. If I am not happy with the results, I might just look into using it for something else

[zeroaxe]

PS. Where do you source your parts in the UK(specifically dual valve springs?). I have single stock springs on there and am SURE I have valve float....

Yes thats it.
