2l Aircooled in campervan.
Last time I checked plugs there was oil on no4.
Coming back from Glasto with van full of teenagers the following occured in this order:
1. misfiring at 45 - 50 mph in 4th
2. Loss of power sometimes
3. Loss of power on hills and 'rattle' from engine
4. Massive power loss on steep hill
5. Plume of blue smoke
6. stop
7. AA man found no compression on 3 & 4, 1&2 Compression ok (125). Oil leak from RH side of engine.
So I guess I am looking at engine out and a head change. But what else should I check?
Also, why did oil appear to come from RH side of engine when head for 3&4 is on LH side? Is there something else on the oil line up that I should check/replace?
Any help gratefully received

Re: 2L A/C; Power loss - then oil loss!
Dear Chris,,,,,,,,I can only assume you got towed home,,,,,so you will have to start from scratch to check the basics before you start taking anything apart.....
From what you have said things don't sound too good but a logical systematic approach will help you solve your problem......
If the van was mine I would be checking all the basics such as oil levels / spark plugs cleaning and re fitting ( and making a note if any oiled etc )
If you have access to a compression tester may also help before you re fit the plugs and try to start her up......
If you are lacking vast amount of compression it may be fair to say you have enough of an engine problem that will need investigating, eg head off at least.
The question is what are you likely to find once the motor is stripped........or do you simply 'Bite The Bullit' and buy a replacement motor or try to fix the one you have ? Bearing in mind a single air cooled cylinder head will cost over £ 250...
Regards

Re: 2L A/C; Power loss - then oil loss!
So I have removed the head from 3&4 and it is knackerd as one of the valves has eaten its way into the head. See photo.
Looking at the pistons number 4 is all caked in oil - broken piston rings?
Number 3 has a big lump missing from it (other photo) - presumably lean burning?
Questions are:
a) can i replace just the one piston and cylinder on number 3 - or do I have to replace 3 & 4 or even worse all four pistons and cylinders (i have not removed head from 1&2, and dont really want to).
b) Can I replace with 2nd hand pistons and cylinders - if so where can I get them from?
c) I have single webber carb thing - how do I tune it to stop lean burning?
I am strapped for cash (my ex wife has it all) and therefore want to keep costs to a minimum.
Any help gratefully received.

Yes but getting a new single piston is not an option as they come in kits as far as I know.... It's possible the piston will clean up - if a valve has been leaking then it will be oily, you may get away with just piston ringschrispee wrote: a) can i replace just the one piston and cylinder on number 3 - or do I have to replace 3 & 4 or even worse all four pistons and cylinders (i have not removed head from 1&2, and dont really want to).
** Whilst it's in bits I would check out the other head/barrels - remember he who pays cheap usually pays twice!**
I 'might' be able to help there but won't know for a month or so!chrispee wrote: b) Can I replace with 2nd hand pistons and cylinders - if so where can I get them from?
put the original twin carbs back on! - what model of webber is it have you had it apart and checked what jets are in it?chrispee wrote: c) I have single webber carb thing - how do I tune it to stop lean burning?
It is by will alone that I set my 'van' in motion!

Re: 2L A/C; Power loss - then oil loss!
Thanks Dugcati for reply.
Have removed head from 1&2 - This head had good equal compression on both pistons and inspection shows no damage to pistons - although there is some oil in the cylinder? Any ideas how that oil got there if compession fine and head seems fully intact? Could it be due to failure on other side?
Have sourced a second hand head for 3&4 and a piston and barrel set - head seems a bit grubby but I am told its fine, Should I have it checked out or refurbished - if so who in my area (Portsmouth) is best placed to do the work and how much might it cost?
Replies so far have been really helpful - thanks to all.
