[quote name='InstructorPiggy' post='52022' date='Dec 2 2009, 09:29 PM']Would need to remove the rocker cover, then when engine cold, check all the gaps between the lobes and the valve buckets, compare to manual/autodata. (obviously when the lobe is pointing away, so the largest gap possible)
Then find the ones incorrect, do the math and order new correct shims.
time up engine.
Remove the buckets that need new shims, remove the shim, replace with new correct size and reverse the above!
Pretty big job!
Duno how he wouldnt know, bearing in mind the shims easily fall out of the buckets sometimes!
[/quote] ok, so almost 1 week since work on car, and now my dad is p!ssed off, once extremely quiet car, now knocking like mad, engine managment light on, temp gauge going mad (no loss of water), smoking alot, no power and no oil on dipstick also 26 miles to £15 petrol!! I had 3 mechanics say its a tappet noise, 2 garages turn the work away, anyway, a mech we know in my dads street is now away and not back until new year, when he said he wil reset the tappets, mech theory, guy who did the car did not put tappets back in dis-assembled order? But why loss of oil? Would bad mpg be due to tappets opening/closing incorrectly causing more fuel being burnt/lost? He renewed the plugs today, 2 good tan colour and 2 black wet, with reduced electrode compared to new ones..a mech i spoke to said best and cheapest way would be get a second hand head and fit that, due to time of resettimjg tappets etc..what you guys recon
