REBUILD - Faulty seal or faulty PUMP?
Rebuilt my 156 2.0TS (bottom end rebuild)
started and ran fine - (5sec trial)
BUT - oil peeing out of NEW crankshaft oil seal at pump
I assumed fault pump or faulty seal
Stripped pump off - disassembled - finding nothing dramatic except a sticky pressure reg piston - duly freed
Thought I'd originally may have tightened pump onto block not centred on shaft (leaving a 'gap' on one edge of the seal - hopefully not repeated this time
Reinstated pump and test ran (5 secs) and - - - - - Oil leak still there
It's so fast that it MUST be under pressure (5ml/sec - guess)
Its not like a punctured vein but it's not 'right' by a mile
ANY THOUGHTS GENTS (and ladies) ?
I can only assume faulty oil pump - but there's not much to go wrong??
The pressure channels inside the are not far from the seal but I guess its fine - normally
- A slight amount of wear would let oil past the rotating faces/sides - but ther was no leak before the strip down (remember - I've used a New oil seal)
Any track record or links to previous experience? ((I'm a newbie on here - and all I get for searches is 20 pages of threads to read through - Is there a better search tactic?))
I'm about to buy a new pump - but I'm curious to know real reason
While I'm having my pounds worth - I've got the cambelt right twice but does +/- 1 notch make a BIG difference to engine performance. There's backlash in all crank and cam drive pulleys - until you tighten them - with 'correct procedure' ) There's even half a notch slack in the camlock blocks
THANKS - in anticipation
anybody who thinks the sky is the limit is just short on imagination
