This is brilliant, I too have explored my 300 and love the conundrums present. Gotta say though - overall, most stuff is accessible without the mega stress. Great vid and very amusing.

Hi Mike thanks for the update and sharing this video. 🤔 looking forward to part 2 👍👍👍

Two centuries from now, one of your descendants will be chief engineer on the Star Ship Enterprise.

Brilliant Mike 😊 Well worth watching you as you’ve a very interesting way of explaining things 👍🏻

Good timing Mike, My winter project is rebuilding a 300 TDI to replace the VM 2.5 in my RRC .

I have seen that gunge before, it was caused by carbon particles being forced into the oil through the turbo seal .

Thanks Mike - entertaining and educational! Really appreciating what you're doing. Seriously - thanks a lot!.

Thank you so much Mike. I much appreciate your helpful guide and insight, should I get to this one day. All the best.

It looks like you are selling fertiliser as aside line Mike !! Lol. Good video as usual.

Hi Mike, another very instructive video!. Here, you say that (seeing the state of the rings) you consider change rings. Once a mechanic (I have to say that I didn't trust much in him...) told me that changing rings (in an old engine) without doing anything at crankshaft level it is not convenient, because there's going to be more compression in combustion chamber, but the crankshaft and it's bearings already have some wearing, so the new "power" in the "up side" will accelerate the wearing in the "down side". It make sense to me, but it is that so? Or it's just a matter of measure the wearing to see if it is under tolerances... (?). Thanks, Cheers!

Well my favorite lil grease moonkey ... squadron leader...that was truly amazingly fantastics ..kinda like gone with the the wind ...nay ..the searchers .. epic ..and no indians were harmed in the production ..😎😁pip pips and carryon

Thank you for your videos, great stuff!

Great video and fantastic site. I’ve just had a crankshaft break on my 98 tdi300 at 145k miles .Not a good advert for a regularly serviced and carefully driven vehicle!! Now had a replacement fitted but was wondering whether to fit a boost pin to pep it up a bit. In your opinion would this be detrimental to the engine and increase wear and tear?My replacement has done 105k miles

very intersting in regards to what you said about the injector pump support bracket, could that cause a timing belt to go?

My issue is: all four effing injectors are stuck in the head, turbo is beyond hope, most bolts missing and i got the crank with a chunk cut off. Might look for a other take out unit that is destroyed low in the engine so i can rob the missing bits and have a spare head. I might get a core unit for the turbo, then go from there.

Any afterthoughts on the 'grunge'? Incorrect thickness oil control rings, or insufficient crankcase ventilation, or poorly machined pistons? (I'm talking out my ass, all I know are petrol Chevy V8s.) Oh, why a bolt to hold the lifters? I've never seen that before. (See above comment!)

Hi Mike, have you any pictures of a piston that's had it. Cheers

Bad oil,bad quality oil or the engine is running to cold?? Gef
