TD5 cylinder glazing

I didn't think you could bore/hone a Td5?

Aren't they ceramic coated or something? :confused:

To give you an idea about cleanliness, I used to spend near on two hours washing and scrubbing a block after machine work. I have a selection of different size bristle brushes for scrubbing out the oil galleries and a scrubbing brush to dislodge crap from the bores using Drive and water.
it was the most important part of a build up IMO, apart from measure, measure and re-measure :D (OK I might have a touch of OCD too :angel:)

Phil, pretty sure you can't get OS pistons for the TD5.

I like to get the bores clean enough that if you wipe them with a white rag the rag comes away clean. No discolouring.

Also re-read the last part of my first post.
Excessive idling can be a sackable offence with some trucking companies.

re-read and wilco - I must admit as an ignorant user I had always thought a good "warm-up" was the right thing to do - not that I ever have time!;).

I am glad my impatience is actual avoiding damage.:p

I still hear trucks idling away while their drivers are having a meal at the truckstop in town.
If they'd have worked for my mate Doug they'd be looking for a new job after their first trip.

i think there is a campain in WA or SA to turn off idiling trucks after 5 min? that should be a national law!

cheers phil

What about idiots that always use glow plugs on direct injected diesels...:wasntme:

ive slapped afew bangers together for speedway that have just been re honed and they all had low spots in the bores from ring and piston ware. its not critical in speedway cos std holdens dont last that long anyway:eek:


there's something funny about this TD5, like why did it need a rebuild and how many k's were on it. and if OS pistons arnt available and the bore was out of tollerance why was it re built??


cheers phil

Phil,
I would have to agree looking at the pics. I am by no means an expert, but have had a few bike barrels bored and a couple of car engines and it is closer to a nice shiny mirror finish. That is almost definatelly a hone job. Have done a couple of these with a mate and that is a similar finish. Not good.
