Big power reliability?

[CJ_Derv]

From my experience, its luck of the draw with XUD's, ive had a stock engine throw a rod, but this was due to the diaphram splitting and drawing diesel into the air intake and the engine ran off and then a few daya later it went pop and that was totally stock.

I had several head gaskets due to a blocked matrix but wasnt as clued up as i am these days and Ruans thread on Not bypassing the matrix is key when it comes to cooling, as any difference in restriction of flow to the head can result in overheating even the slightest overheating can cause problems.

Iv been running 28psi on TD04 for a good 6 months now and 169bhp 240ft lbs and hasnt really ever gone over 85 degrees coolant temp, its due a service. as ruan says it is very noticable when you need to change the oil, i can certainly feel a drop in power, i use 5w40 fully synthetic cant remember what brand but its good stuff.

Ive always found if you service regulary and dont thrash it every day you stand a chance but for what they cost its worth having a spare block to hand IMO

As for clutch im running a standard one atm but will be putting my lightened flywheel and new cg paddle on in the next week or so with new cable and fork arm bushes
