help!!! 2.5 TD head?

[madmark]

its very unusual for a di to suffer with stem seal problems are you shure its not pump problems????????? is it hunting ????and is the pump timeing correct???????? this sound as if its feul problems blue and white smoke form the exhaust , i have never seen a di with stem seals gone yet!

[100ps_drw_hicube]

according to 2 different garages its the valve stem seals as it only done it for 2 mins from when cold ye the pump does hunt a very small amount hardly noticable not sure about timing i have got to get the belt done soon as i have no history with van but the mileage is guaranteed at 80k anyone no how much to fit belt i have got belt and tensioner from ebay only 12.50 inc p+p gen ford as well also do you have to get the pump coded to the key??? as i have another pump from a 10k accident damaged van so should be bloody good

[madmark]

mate mosts di,s do smoke a small amount ,with only 80k on the clock i think the problem is elsewere! when i first started my td if a reved it up it smoked abit of blue as such but then cleard and then nothing attal out of the exhaust!

[100ps_drw_hicube]

ok i believe you as you have more experience its just my dads got a identical van to me but has over 230k on same engine not a single puff of smoke!!! could the smoke be linked to the problem of power loss if you switch off after a short run??

[100ps_drw_hicube]

here is my 1st post copied

i have 2 problems really the first being when i start the van from cold if you rev it to pull away it blows thick clouds of blue smoke but if you leave it idling for 5 mins and rev it and pull away its fine no smoke at all the other problem could be linked but i dont know when i start the van from cold or i have left it a long while it drives with full power if then i stop the engine for any reason and restart within 10 / 15mins it runs but with no power at all it is as if it were only running on 2 cylinders or similar but it is really slowing me down now so its time to do something about it i have been to a ford dealer who tell me they cant find any problems with it
has anyone else experienced this? it is a 2.5 td 100ps lucas pump and fly by wire throttle if that is any help?[/quote

p.s fred seemed to think the rings was what the 2nd problem was and the 1st was valve guide seals??

[Luke]

When the valve guide seals go it tends to be worse at first due to the oil that drains past them into the combustion chamber overnight. When the engine starts all this is instantly burnt up - hence the smoke, as the engine gets warmer the valves heat and expand closing the seal and also stopping the oil passing! hence no smoke!

personally i just live with a problem like this untill it becomes much of a probelm!! which eventually it does!!

the problem with valve guide seals is it wont show up on a compression test as the valve does the sealing not the guide!!

[transitgeoff]

never heard of a di with stem seals gone, i think the cvh had the monopoly on that

[bortaf]

the main reason was the head was cracked at the back the exhaust manifold was cracked and the valve seals had gone + there was slight trace of water in oil


since i have changed it it dont idle very high sort of hunting?

I had similar but it was a lot of water in the oil, when i say a lot i was doing 500 miles a day in it, for instance : London to swansea to cardiff then the brecons and i drained half a plastic coffee cup of water out of the sump drain plug after it had cooled down but topped up the header tank with over a litre of water .
I changed the head twice, with known good heads from running engines (cost me £250 quid to find this out in heads, gaskets,new head bolts ect) then descoverd/decided it was a cracked block
On one of the head changes i must have bashed the end of one of the injectors because it smoked like a trooper and ran rough(on 3 cyl) changed the injector and was fine.

[madmark]

mate how long does it take for your engine management light to go out?????? (should go out as soon as it starts) and also have you had it pluged in at fords?????

[FredTransit]

We have 2 engines that are in their 3rd vans! Niether of them has major oil smoke, and a little smoke on start up, than it goes. it's expected in older engines. Never touched the internals in either of them!

[100ps_drw_hicube]

have tried different injecters, there is no oil in water since i put the new head on, the engine management light stays on for about 3 seconds the owners hand book says this is the correct amount of time, i have had i plugged in at a ford garage but they couldnt find out what was wrong with it but then they are useless took them over 4 hours to code a new key??? have just got back and the sun has come out so will be working on her for the rest of today to see if i can sort this problem out

[100ps_drw_hicube]

almost sorted now upto about 97% full power back, lot of black smoke mid throttle but no other smoke at all i re tightened head to 85 nm shouldnt do any damage should it i think the rest of the power loss could be the turbo needing seting up??? also where is the best place to go to get a cambelt done ford garage or mobile cambelt service??? also what is a rough price for fitting i dont want to get stung

[MrMPuk]

2 hours labour is the most that I would pay, if they charge you more than that then they are over charging you!

so it was the headgasket not torqued down enough!!
if its been running hot gas must have been passing it! is it a new head gasket? if its the same one i wouldnt expect it to last a long time!!

[100ps_drw_hicube]

ye new head gasket still at least i know for future head to be tightened a lot more than ford says!!!! hopefully all will be ok now until friday then the dreaded mot hope the new plate satisfies the tester then next week i got to get the cam belt done i will try and get some more pics on this week if you want
