Valve guides, regular old factory sized not oversized, not unicorn spunk spattered, for a very popular engine (almost any VE/VP/PD VAG group diesel of 1.4/1.9/2.5 from 1990 to 2005).
Does no one rebuild engines anymore?
Could get hold of the right size and spatter type crank + big end bearings, the correct bolts (actually going to 12.9 instead of 10.9 because they be only OK for standard power), gaskets, piston rings, cam shaft, seals everything. But valve guides, really struggling.
TPS/VAG group parts company I have an account with, they 'CAN' get them, but at £23.xx + VAT each I would just stick with my 260k mile half worn to limit examples. They should be all of £2-4 each. TRW or INA did most of the head components originally.
Spec sheet says 1.3mm (which is 0.65mm either way of centre) movement at head of valve measured side to side with a DTI is the max. I'm getting 0.5 to 0.7mm (total) across all valves. Valve stems are almost measurably unworn, so just the guides. New they are 0.1 to 0.3mm. Half the reason for the rebuild is wearing cam shaft + oil out of torn exhaust valve stem seals (caused by age, mileage, and possibly a bit too much valve stem movement).
Anyone had much success with trying to get cylinder head rebuilders to sell the guides supply only?
