300 Tdi Engine Replacement


Jim Mason

Recommended Posts

Might need help here, never swapped out an engine before but cannot afford garage prices.

Im a field service engineer by trade so got tools and knowledge etc.

Most of the old engine is stripped ready for removal...

Replacement engine photo's attached.

Need to do timing belt change what else whilst its out of the engine, financies are tight.

Whenever an engine is out, timing and rear crankshaft seal get done regardless.

Clutch is completely replaced.

In doubt, slave cylinder is done, too.

Once back in. warm the engine up and do a full service

How do i back flush the cooling system?

What methods work?

Started cleaning the engine down yesterday with Diesel, most of the muck was coming off...

Seems most of it is road film, engine never lost any oil according to previous owner and belives it came from else where... prop shaft seal etc.

If you look at it and go through , in your head, everything minor that can go wrong, be a pita and should be part of the regualr maintenance programme. Replace nuts and bolts that look iffy, jubilee clips etc - and make a list of what you didn't change that you need to change as and when you have some readies

Traffic film remover is wonderful stuff.....

Oxalic acid in the cooling system is fantastic and cheap on ebay, often sold as wood bleach.

So the Oxalic Acid is a rust remover, can this be used once the engine is back in and running.

Presume traffic film remover is to clean the block...

Weather gone nasty on me, need to work on engine in garden umder a gazebo.

I know from previous jobs if its too cold you cannot work on metal as it needs to be a certain temperature.

What are everyones views on this...

Engine is outside, covered up, how long can i leave it like this?

It is never too cold to work on engines -even to the point of scraping ice off the tools, you just need to work harder to maintain circulation.

Depends how disassembled it is, whether you have plugs all orifices (plastic bag and cable tie round inlet, get creative with anything else that means moisture can get in), and how well covered it is.

Personally I'd just get on with it and get it in there and running ;)

Moving on, cold working on engine outside...

Few more horrors found in this engine ive obtained, engine not had any anti freeze in lots of corrosion present, removed core plugs to find silicon and remains of a gasket.

All slowly being cleaned & replaced
