dunno why i did not take a picture of the head its really nice and well new :)

soo enough of being happy about that, can anyone recommend a good head gasket as a replacement. my old one gave in at a really weird place so just want to try and get a good one so not to repeat this again.

Also i just want to know whats the trick in getting the turbo off. i got it off in the end but it was a very violent fight :)

Payen BK 450 is the gasket to have, make sure the head surfaces are spotless and flat.

Most decent motor factors will deal with Payen, they will order you one for around a tenner.

As for the turbo removal you often have to be aggressive!

JF.

if you wan the full turbo head gasket set with the proper manifold gasket get your motor factors to order you a payen DK451, thats the full head set and costs around £25.

My turbo ususally falls off, just undo the top steadies and wedge the engine forwards, i dont ususally undo the downpipe clamp either. then i just sit the turbo in the bulkhead box, works a treat.

so is it DK 450 or 451 :)

how do you undo the small hose that runs from the back of the block to the bottom of the turbo normally, i couldn't get it undone. also do you remove the down pipe or just disconnect the middle sectionand bring the down pipe out with it, i only ask as the genious before welded the down pipe to the middle section and as i couldn't get to the clamp on the down pipe to turbo to release, lets just say an angle grinder was used....

well just spoke to Avonbar they recommended the rover gasket so went for that and for a gasket for the manifold also at 1.95 something....bargin....

just looked at the turbo also and i got some play in the shaft. think that means a new turbo doesn't it?

BK450 is the part number for just the head gasket, DK451 is the code for the complete head set.

At £1.95 that'll probly be the injection fannymould gasket which should be ok.

a decent 1/4" drive socket set comes in useful for the downpipe clamp

there is always some play in the shaft, if it doesnt smoke dont worry

Play in the shaft, which direction? Axially or laterally?

i think the movement was side by side, and yes it did smoke on start up and when came on boost :(

Axial or radial

Well if its smoking on idle and boost then its likely its rebuild time. Although i wouldnt go doing it just yet incase its something else. if its not too bad get it back together.

just on start up and boost not on idle (i think), all these long words, think i will get my dictionary out later and have a play with it

while the heads off stick some guide seals on .

the head has bronze guides is this what you mean.

T

no taz .. on top of each guide there is a black rubber oil seal , to replace them you need to remove the spring with a spring compressor and pop a new one on the top of the guide , its a classic place for minis to leak oil into the chamber and so create smoke . of course if its a new head or not v old then the seals would presumably be new and not need changing.

i believe the head to be relatively new, i'll get my mate to have a look for me as he has more knowledge on this kinda stuff than me....trying to learn but its a slow process.

i'll get some pics up aswell, so you guys can tell me what you think of the work done on it being the ppl in the know and all :)

Just ring Avonbar again and save everyone else's time on the forum!

JF

wel bit late now maybe do for tomorrow..

although your help is really good etc etc and i do use the search function, you knowledge is a lot more than mine thats why i ask questions.

sorry if you think me annoying but isn't that what the help needed section is for?

i dont find you annoying at all taz , we all started with no knowledge at some point in our lives
