Vw t4/lt/crafter all use 5 pot diesels, different models but the 90s ones generally more sought after.
Have the same engine in my 90s volvo, just done bottom end after it needed piston rings (gummed from using veg oil), decided to replace crank and rod bearings (with factory spattered type), after 260k and 22 years they were fine. Some measurable wear but not terrible, nice and even, no scouring, no anything really. Polished the crank journals and put new ones in along with one grade higher of bolts.
The high power guys are running massive steel plate girdles across the main bearing caps (20mm thick steel!), double squirters, forged h beam rods (forgot brand), a chunky decompression plate and then very serious heads, they've been chopped up, dissected and bits somehow welded in to increase everything, amazing really.
Cast iron all the way!

Yeah i read up a bit on them after i originally posted, I'd sort of forgotten that a lot of the T4 etc of that era had a 2.5TDI version which was 5cyl.
I'd actually quite like a T5 sportline as it is!

The T4 5 pot diesel is an amazing engine due to it tolerance for abuse and lack of maintenance. As I have mentioned before.
Were you using svo or mixing it? How long before the engine suffered sticky rings?
