I have a lovely old merc m/h, BUT on my last run out to Rutland it started to smoke....Badly... Some may remember lol...
Im considering having a compression test done, then taking the head off and having the valves done etc... This will cost... i recon £750 min.
Hopefully this may will cure it...
I have priced up a recon... 3K plus... to much for my budget and that is what the m/h is worth now to my guess.
Or I could save up and buy a van to convert and put all my things in it, out of the m/h...

What would you do?

Id say have a look around and see what the MH is worth, if its worth a bit, they do hold there prices well, id get it fixed. Buying a van and converting it will cost more than the £3000 for a engine recon too.

i would fix the engine. a reasonable s/hand van will cost 2-3 grand, and a diy fit out,even with the old bits, will still cost 500 to a grand. then you'll have a faster smoother ,more fragile van that'll cost you major money every time it goes wrong

I personally would go the cheapest way first, ie there is some stuff on the market, my garage used in my van when they last serviced it, I think its called FORTE or very similar, pour it in the tank and go for a very long run (I went to Italy on holidays) soon I started to drive in France I think that stuff started to work as I could feel the vans engine pulling a lot easier and not even a puff of smoke when changing gears, it only cost about 10/15 pounds I think. If it does not cure your smoking then I would take the head off and have it reworked, ie, planed, valves changed. valves stems and seals and perhaps even new valves but any good engineering workshop should be able to know what needs replacing. and with the head off you can check the cylinder bores for wear and if the sump is easy to remove perhaps even the pistons pulled out and rings checked , obviously by having a compression test done before you start dismantling you should know the amount of work required to put it right. Hope you get it sorted whichever way so you can continue wild camping.

Can you find a decent second hand engine?

Edit to add a compression test probably won't help.

If van is in otherwise good order, I'd keep it and get it fixed. Tidy T1's are worth keeping and looking after.

id be looking for a used engine from a scrapped van.... even buy an old van to rob, a small independant garage should be able to swop engines in a couple of days easily, and may even be able to source an engine.

few years ago i did the job on an ldv van, used engine from the local scrap yard and a few pound notes to a student friend of my sons to fit it.

What colour smoke was it?

It is not difficult to overhaul the top end. Lapping in the valves could make a big difference. If the problem is with rings in a cylinder, you should see which one by the state of the valves (poor compression).

You could first try the Forte engine cleaner as it does work well and will remove Carbon deposits if you go for a good fast run.

What is your air filter like. Remove it and go for a run to see if it has made a difference.

It's very difficult to diagnose a fault without seeing it at first hand. Start by doing the simple things first.

Compression test first, then consider the options. A compression test should highlight whether the top end or middle is causing the problem, and if it is not from the actual motor. It may be caused by ancilliary parts. Get some idea of costings and look for a van similar to yours in the usual places, Ebay, Gumtree, Autotrader, to get a value. It would be worth checking the state of your chassis, body and interior to see if there are any possible future repairs needed. Write everything down and do the sums. Consider the hassle involved in any future plans as well.
I would say that to do a van conversion to anywhere near the specs of a coachbuilt will cost you several thousand pound, and a lot of time.

as tompa says.
Compression test first, then repair your engine, better the devil you know. buying a secondhand engine could lead to more problems than you have now.

Forte Forte Lubricants - Forté UK Home page (http://www.forteuk.co.uk/home) is a brand name for a firm that does additives, among other things for the motor industry.

An oil seal conditioner additive could revitalise among other seals valve stem oil seals temporarily but in the long run is not a perfect repair.

Engine cleaner additives can cause more trouble than they repair!

Some scrap yards will swap your engine for a secondhand one and give you some warranty.

A compression test won't tell you if oil control rings or valve stem oil seals are leaking.

The question of what colour smoke is a good one.

Just had it running and the smoke is grey...
I run it for a good while and the smoke was constant...

First make sure you are not losing any coolant then watch to see if oil level goes down much,if not it could be a sticky injector.
White smoke or steam after a run head gasket if losing water,blueish smoke is oil burning ,cylinder wear or oil control rings worn or stuck & also valve seals,blackish through to grey is normally injector problems.
It would be advisable to let someone who knows these engines to have a we look as it may save you money in the long run.

Have you checked that the breather pipe etc is clear and not blocked or collapsed

Yes and if it is she will blow oil out the dip stick tube

Check back pressure, open the rocker cover cap and see if she's blowing much out there that's a sure sign of gasses escaping past the rings

i think i have checked everything else.
Not loosing water or oil..

It could be the diaphragm on the injection pump.Can be replaced in situ.
It will not be the head if it is not using oil or water

Before you waste hundreds of pounds find a mercedes specialist because those old mercs are bulletproof engines and it is probably something as simple as a blocked EGR valve!!!

it isn't losing water or oil and no mention of mechanical noises (knocking etc) so don't waste your money on a refurb that it probably won't need until it has been around the clock

I know a garage owner/mechanical genius who loves these old merc engines and you can ring Peter on this number 07731085246 and tell him that Ian has told you to ring him for advice. I used to work right opposite his garage in Lanark before I got ill last August and often popped across after work to see him and have a chat. I sold him a smokey 2.9 merc Sprinter 310 and within a couple of hours he had cured it

Give him a ring (its a pity you are so far away from him) he might just know what the fault is over the phone

Ian (Arnolds driver with :dog: if he asks)

Oh...
I thought valves....
Is it hard to sort the diaphram out...
Could do that first....

Will phone him tomorrow......Thanks very much...
