Suspected Cooked TD42

[huey_gq]

Hi everyone, i have just recently had a mishap with my GQ patrol. I left the radiator cap off and warmed it up a little much. The main reason i am posting is to find out if anyone has rebuilt there TD42 using roodogs spares parts that are advertised over ebay. I need to either rebuild or replace my motor which for lack of a better word is f****d. I cant seem to find another motor worth buying in fact its very hard to find a second hand motor at all. The cost of a second hand motor is around the $2,500 mark but rebuilding would probably take it closer to the $4,500 mark even with a mate as a mechanic, considering the machining needed. I love my car to bits and need to get it going again!!

So any comments, prices, dealers, wreckers, experiences, etc that anyone wants to reccomend would be greatly appreciated. Located in Castlemaine Victoria.

Thanks in advance huey

I know someone that did a similar thing...loaded up for a big trip - to the other end of the country, and then did a last minute check on the radiator, and in the excitement to get going, left the cap off.

Stopped a few K's down the road, but it was all too late.

$5K and a couple of weeks later, they were back on the road.

Hope you get it sorted quickly

Mate your better of buying another engine as your cooked engine will most likely have other issuses even after you rebuilt it

Nothing wrong with ROO DOGS SPARES, they may sell a complete rebuild kit to suit your needs

So I have pulled the big girl down now. Head seems good, and straight. Pulled all the pistons out and found that number 2 piston must have picked up in the bore in the moment of overheating. The piston is buggered, bore looks pretty ordinary too. Was just wondering if anyone has used a finish sized sleeve to replace existing buggered one instead of a semi finished one that requires finish machining??

[johno90]

nothing wrong with finished sleeves aslong as everything is standard. i always use semi finished tho as any modifcation to the piston needs to be account for and then can be machined to exact size for the piston in it.

Well i've done some ringing around and sorted out getting a rebuild kit with 6 semi finished sleeves then getting an engine shop to remove and fit them then machine them to suit. Another thing i was wondering while the engine is out what holes for turbo oil feed and return lines will need to be put in to accomodate a turbo in the near future. I am building this engine to suit a turbo during the rebuild. It doesnt cost too much more so why not.

Got the block re sleeved and bored etc and have started to re assemble. All gone smoothly and there was only a week turn around on the machine work through HM gem in bendigo. The price tag for the new sleeves to be pushed in machined and honed, con rod bushes fitted and machined was $1670. That included all gaskets, orings, bearings, pistons etc. I was very happy with the price considering it was close to $3000 for a second hand motor that you really have no idea of its history. The kit comes with pistons with alfin ring grooves that can be used in turbo applications. So i guess i know what the next project will be...

[threedogs]

so far , so good keep us posted

Nice one mate.

You did not happen to take a heap of pics did you? I'd love to see the internal damage and the rebuild is a thread. Would be interesting and a great asset to the forum..

Cheers and good luck with the end result.

I only took a couple of photos of the damage beforehand. The engine is at the stage of having the crank and pistons in now and i haven't taken any photos yet. I will start to take photos from now on to try help everyone else out. To this point i have only just followed things by the manual that i downloaded off here. It had all the correct torque settings and i also have a big tip for everyone. When fitting all the moving parts that require oil eg main bearings, big end bearings, oil pump. I used a good coat of LUCAS brand assembly paste, i was told not to rely on putting a film of oil on these because it could take a while before the engine is running and the oil can escape and leave the bearings etc dry.

If it was turbo charged, get the turbo rebuilt. I'd also change the glow plugs. The other things the engine rebuilders I deal with do is change the injectors and often for warranty, they get the pump serviced/exchanged.
