2L-T Engine Work - What to do? (1 Viewer)

[Syzygy]

My 2.4 turbo Bundera has done 250,000km's with no engine work as far as i know.

I have a feeling that its getting a little tired. It rattles a little more than it used to and blows a bit more smoke than it used to. generally just doesn't go quite as well.

The injectors were cleaned around 50,000 ago, and have had regular doses or injector cleaner (which i actually think helps). Oil had been changed regularly and the turbo seems to be working properly. Theres nothing obviously wrong with it as far as i can tell. Appart from some lose tappets i'm told.

So with a small budget, what should i have done to it? I know very little about engine internals so i have no idea at all. What are the common faults with 2L-T's? whats likely to need replacing?

Not really interested in major rebuilds, just more of a major service to keep it going strong and prevent anything failing...

when was the timing belt changed last?

My advice is to get the compression tested so you have some idea of the condition of the engine.
Then make some hard and fast decisions.


Fixing bits and pieces only to have it die in a heap is not really an option either.
The labour cost to dismantle and fix individual internal items can be similar to the labour involved in a full rebuild.

This could also be just an injector pump problem .
Blue smoke is an indicator of oil burning which is usually worn out rings

250000 is not overly high klms for a 2LT so it may have some life left in it.

Also consider posting up in these forums for more information. While they may not be Bundera specific, they all have information about the 2LT.

what color and smell is the smoke ?
Its always a good idea to adjust the rockers, maybe it's injector time as well.
If you have to do anything preventive about your engine, I would focus on the cooling system.

This site details recommended maintenace procedures and intervals for the 2L-T and 2L-TE. It's quite good - worth checking out.

i read that site regularly

there is quite a lot of white smoke on startup, but its only 1 big puff. 2 seconds and its gone. Then its just the normal black smoke while driving, but i'm noticing more now than before. Still there is a fairly small amount. nothing to be too woried about i dont think.

The cooling is getting a bit of an overhaul, but the standard radiator is staying. Have just fitted a snorkel and an intercooler is not far off being fitted.

I think the point about labour being so expensive is a good one, I'm probably best of getting a full recondition if they're going to be pulling anything apart.

perhaps i'll just get a compression test done to check all is ok...

thanks for the links too

The Bottom end on these engines is pretty strong, check and adjust the tappest or get them done, get a compression test. put some Wynns stop smoke in it and see if that helps, may well help a little if the rings are on the way out, however if it is just black smoke when running I wouldn't worry too much, probably the injectors are starting to weap - might be worth having them reconditioned. White smoke on startup probably indicates that you need new glow plugs - if it continued for a while I would suspect water in the combustion (cracked head or head gasket gone) but as it stops and there are no other obvious problems indicating this then I would say glow plugs.

I sould fit a new timing belt and while you have that off check and replace the water pump if it is at all suspect. The water pumps only cost a small amount compared to the damage if they let go and the engine overheats.

Apart from that I would leave any majro engine work alone. The tappets should be direct actuation ones without rockers unless it is an early engine in which case they have rockers and are adjustable. The direct ones need shims and are probably easier to get a shop to do it for you.
