so today picked up my next engine job i dropped it at remapper yesterday to map it before i take it apart so gave me a chance to do a full diagnoses on it , it got ok oil pressure , but that where things stop not so long ago it had a coolant leak and got over heated so i today done a simple test where header tank top off ran engine hot while cap off and kept adding water so coolant right at top of tank so can see the bubbles ,, and yep as it got hotter it got more and more bubbles all signs of cracked head ie very common when these engine have a coolant leak and air gets in the head,, i also found in the sump debris from a past timing chain failure as per pics ,, also found where a garage had over tightened the turbo inlet pipe and broken the plastic insert then the broken plastic has destroyed the blades on the compressor of turbo ,, i should eb able to fix this with a new chra centre part of turbo and new inlet pipe , i also have a used compressor outer somewhere incase the old one is damaged inside, i checked the sump and no white metal in the bottom thats a good sign, also found oil pump chain so loose its nuts and why who ever done the timing chain last year never done that chain as well is beyond me,, i also as per pics found the timing was 3 teeth out chain was done by a garage not long or many miles ago and going by the guides would say under 10k ago,
below pic spark plugs total eaten by oil some of other were pink ie anti freeze from cracked head
below 1 to 4 plugs different colours from different issues in each bore
surprised this drove from midlands
above pic shows how far timing was out on it its funny these days i can drive one for 10 seconds under load and just know its out or not,
above timing so out, also the tensioner was a fair way out so chain is stretched ,
above pic is of the damage to turbo from debris off the intake pipe from someone over tightening it mostly,
above pic of intake pipe and its damage that nailed the turbo ,
above pic of another load of parts for a mini engine,
