OK, if anyone has suggestions great :-( as I really am trying hard to keep this one alive!!
2nd Gen surf= 3.0 Turbo Diesel SSRx-Limited auto KZN130 on an L reg 1994 138K on the clock.
Original Problem: engine gets hot very quick and overheating on hills and under load with lack of acceleration, very lumpy on start up, but revs ok, plus the loads of black smoke.
So far this is what 2 garages have tested or replaced between them.
Coolant System was pressurising so changed the following.
New Thermostat Toyota original plus coolant flush.
Cleared out expansion tank full of gel.
New Radiator (Steel kind) plus coolant change
New Radiator cap
New Head gasket (5 hole kind thicker) + New AMC Head with new shims / cam
New water pump
New timing belt and pretension
Viscous fan checked and tested all ok
Glow plugs checked and tested all ok
Full oil and filter change + airfilter
Gearbox ATF needed changing so was done along with the torque converter drain.
Engine still getting hot very quick and overheating under load / hills and struggling to manage its own weight and very lumpy on start up, plus loads of black smoke.
so tested the following:
Injectors all checked and tested ok
Injector pump checked and tested down by 5 degrees so needed a new aluminium housing which has been changed.
Injector pump now working correctly and advancing how it should.
EGR valve blanked off.
Engine still getting hot very quick and overheating under load / hills and struggling to manage its own weight and very lumpy on start up.
so tested the following:
Compression test on each cylinder:
Cylinder 1 = 585
Cylinder 2 = 485
Cylinder 3 = 495
Cylinder 4 = 240!!
Cylinder 4 is the latest issue. Garages think it could be a bent conrod or a porous block? I think the block could be cracked, but if that was the case surly the gases should be going somewhere and coolant system appears ok? Garages have checked all the valves which are ok and are now going to check piston protrusion.
Anyone out there had this level of issues and get to the bottom of the issue?
Anyone every had a cracked block or a cylinder with compression down?
I think I could be looking at a whole new bottom half of the engine at this rate, as all the top half has been replaced
I will see this through as I love my surf but all helpful comments greatly received and any ideas as to what is better? to just replace the whole bottom of the engine or just the block and conrod if that's what it is.
Hope this helps fellow surf owners who may have wondered what that overheating issue was? so far for me its a combination of neglect and hospital passes.
cheers Matt
This is my 3rd surf :-)
