Hello,

I want to buy a T25. It is 1980 with a 1.6 petrol engine and it is good condition.

The seller is saying that the the engine is not compressing anymore and for that reason the camper is acutally not able to move.

I am not an expert at all and I would like to know if an engin replacement will be easier and cheaper?

If so do you know somebody in or around the London area that does the job?

Also somebody could tell me apprx how much would the replacement, including a new engine, will cost?

Thanks a lot to everyone,

Best wishes,

Triwy :ok

Hello,

I am reaching the end of a major engine rebuild for my 1981 1600 CT engined T25.

If you look in the various on-line catalogues you will see just how expensive a replacement engine is!!

Take into account your labour and effort in removing the engine, stripping down the cowling, alternator etc., then cleaning off the encrusted dirt....which you will have to do before replacing with a reconditioned engine, then the rebuild and re installation afterwards, and you will see that this can be a pretty major investment.!!

Working week ends I have completed this engine to my satisfaction in about 2 months.

However, a CT engine is a rather elegant solution to the shortcomings of the classic beetle engine, and parts are readily available.

If you do not know much about motors, take someone with you who does, a well charged battery, jumper leads, a selection of tools including a spark plug spanner, also a compression gauge and a squirty can of engine oil.

Test 1. Does the engine turn over on the key? If it turns freely proceed to the next test, if it locks up .. walk away.

Test 2. Are all the rockers moving? Disconnect the ignition at the coil. Prise off the rocker boxes with a big screwdriver and then watch the rocker arms as the engine turns over. They should all move up and down regularly and with the same displacement. If one or more do not move, try pushing the rocker firmly on the pushrod side. If it is squishy and springy, then the hydraulic tappet has let go ( not serious).

Test 3. Take all the spark plugs (4) out and screw in the compression tester to each cylinder one at a time. There should be a reading of between 80 to 150 psi. on each one. If not, unscrew the compression tester and squirt some oil into the cylinder. Repeat the test. If there is a significant improvement, then there is a problem with the piston and bore. If no improvement, then the problem lies with the valves.

Remember, a CT engine is mostly beetle for parts, so not too expensive. Just Kampers understand and can supply the differing bits, eg oversize pushrod oil seals.

There is a Haynes for this engine model.

If the vehicle is good , why not consider selling the CT engine , and fit a 2 litre.

I will be putting a series of little films showing the specifics of CT build up on the net this autumn.

I'd be happy to build your engine for you, but I'm in Central France!!

Cordialement,

John.
