Help - rough start & run until warm?

[dmarkham]

Just about to order the rest of the shims. I'll update next week once they are all back in and see if my problems are cured.. or not.

[ADarbon]

unfortunatly the thing with trile and error I only sugested shims because it was the cause to my problems just hope it is yours too so you can relax and enjoy your bus.

[dmarkham]

Well the clearance (or complete lack of them) were way out and would need doing anyway and there a relatively cheaper option than starting to replace diesel pumps and injectors which was the garages trial and error method - (and of course I may still end up going doing this route). But at least I am learning something new by doing the valve clearances.

I've replied to your email about sending spare shims down to me as I could make good use of them. When I've finished the job I'll list the sizes of the ones I take out if others could make use of them.

there in the post as of monday I am going to start a thread for spare shims just add your sizes too it try and keep it together will make it easy for other members to find there sizes

Just to up date this thread - shims are now all in and checked gaps which are all within limits. Over next couple of days I'll be piecing it all back together and testing to see if the problem is solved.

Just one question if anyone can help - With the cam/rocker cover there is a seal/rubber gasket do I need to replace this or clean in any special way or apply additional sealants before refitting?

[ADarbon]

If the rubber still looks in good condition then just clean up both serfaces get some gaskit sealent and smear all round and replace go easy on the cover bolts they dont take much to snap, I found hand tight and just a quarter turn seems to do the trick. Ive tried the recomended tork setting and they snapped.
If you want to get a new gaskit easily obtained on ebay jap auto  or motorfactors should do a blue print part for it

Thanks for advice on gaskets and good web link.

I've now put everything back together on the bus. Then after a few anxious thoughts (of what I may have left ondone etc. ) started the bus and took it out for a test run and .. guess what ... YES...problem fixed no more rough running - JOY - RELIEF. Ran from cold this morning fully loaded up with children and no problems. So the advise on here to do the valve clearances was spot on. I'm so so glad I didn't let the diesel (expert) garage start replacing injectors and fuel pumps as they suggested. In the process I've also learnt a lot - which includes fantastic support on this web site - thanks .

Hopefully my thread and pictures may be useful to others.

Cheers

Well done Dom glad all is working well and has made the fix much cheeper. some times experiance out ways the brains of garage grease monkey but hay where all APES here.
If it's ok with every one else i might just make this thread a pin up to make it easy to find for other members.

congrats on another happy bus! have been following the thread with interest. has given me the effort to have a look at my clearances next week end. The bus does start too bad at all but as I am running veg it might be worth a look at!

[dmarkham]

Well just to complete this thread I can tell you I've been up in Northumberland on hols. fully loaded up, couple hundred miles and all running well.
 
I can also add one thing for anyone that might use this thread as a guide to doing shims. I did find that when shims are removed if you try to turn the engine the cam lobes get stuck as they hit the buckets (just getting the hang of all the jargon now) so don't be tempted to force the engine round if you get resistance when turning it over to refit shims.

Having read Paul's similar problems it seems shims should always be checked some 12 months after new head refits.

Happy days again in the bus
