I want a GU 42 by Christmas 2022! - Options and discussions on buying a used GU TD42

[wagu89]

Having owned a td42 gq ute for years (was reliable as!!!) And stepped up to a gu crd St wagon mainly for comfort reasons on long trips the crd has proved to be a good motor in the 90k iv put on it so far!!!! (Car now as 255) and since having a custom remap done 2 years ago has more than enough power and has been reliable as for the most part. I do have catch can egr block boost controller etc though.

Ok, ok... IF I happened to go look at a converted td42, what are the danger areas? Let's say everything looks neat, there are receipts and quality parts used. What are some good questions to ask?

Also are there any gu models that DON'T make good conversion candidates?

Check it's registered as a TD42. If it's not, you may have trouble registering and insuring it.

Just check everything works . . Glow plugs work as factory plus ask for a cold start, tacho especially below 1000 revs, all dash lights like oil pressure fuel filter water trap, AC working, sure there's more can't think of right now lol. . .

Also just pay a close eye on the standard of work eg wiring and general tidiness of it all. . .

Check really well where the engine mounts are welded to the chassis as well.

Probably not quite right, but many folks complain about TD42 engines overheating their ‘water’ (kettle’s I believe called) Lucas Mate. Again, poor maintenance I truly believe, albeit they were designed poorly in their systems out of the factory (running on the razors edge even almost perfectly clean) but I do worry about converted ZD30 <> TD42 ones as they appear to have more troubles than most?
Maybe there is a radiator difference or top and bottom hose modification flow problem, really not sure Mate

FWIW: Flew into Mexico from Newcastle late last night, finally gave up trying to fix/find basic old school parts for the petroleum/electrical based Maverick GQ TB42 pimped up 45 after 2,000kms of horrible work Gremlins
In fairness the torque monster 4.5L petty kept chugging at 1/10th peddle but was looking like taking a week to get home for Taco night
Not being rude but my experiences of younger days running Toyoda 2F’s and Chev’s came flooding back
TD42-T’s with the leastest of wires have never before let me down, touch wood 🪵

One tiny fragment of advice I can vouch personally is the gear chatter rattle the TD42's have down-low in the revs when taking off. This is normal!!
Just about every TD i've driven does this.
To the unknown, including my self when first drove it I thought the gearbox and/or the bottom of the motor was gonna fall apart any second.
Don't know the science and physics behind this but don't be put off by it when/if you test drive one and this happens.

In summary "TDs are a good thing" . . .
