Looking at buying HJ75. 2H engine knock?

Good evening, everyone.

This afternoon I went and took a look at a local HJ75 ute. It doesn't seem to be in bad condition for it's age but it does have a bit over 600,000km on the odo. The guy had it running already when I arrived, apparently he had to jump start it as the battery had gone flat from sitting around parked for a while.

I noticed an intermittent engine knock while it was idling. Apparently the guy purchased it 4 months ago but wants to buy a 79 so he fits in it a bit better (I'm 6 foot and he had a few inches on me).

He has serviced it and given it a flush, which he claims has improved the knock situation. It hasn't been driven since the service so he thinks a long drive combined with another flush should bring it good. I'm not a mechanic but my better judgement is telling me to steer clear and ask some people more familiar with these motors.

Another thing I noticed was an occasional spark from the exhaust? I only noticed 2 or 3 within about 10 minutes. What do you guys think? He's offering it to me for 6 grand with a roadworthy. It has a brand new windscreen. Apparently the gearbox, suspension and shocks, injectors and fuel system (previous owner - no receipts). He's also letting me pay it off at $500 per week.

Any input on this intermittent knock thing which has me worried will be much appreciated.

Thanks.

Ben

Hi Ben,
Sparks from the exhaust would indicate a valve problem.
Maybe a burnt exhaust valve.
That plus the knock says to me to steer clear of this one.

It sounds dodgy - engine already running, no receipts, 600,000ks, Toyota spare parts prices.
I'd keep looking.

I'd say he bought a lemon and now wants to offload it.

Yep - and the more vehicles you look at the more expert you become - when you do eventually see a good one, you'll know it in an instant. Agreed too, re the comments on potential $ drama for you...it might be a 'simpler' engine compared to current models, but if the donk needed a decent overhaul, you'd be aghast at the costs. Good luck with the project.

Thanks for the replies, everyone. You've confirmed my suspicions. I'm going to have a look at another one tomorrow with receipts for the 2H rebuild and various other work it has had. It's a 1 owner vehicle and the bloke is a mechanic. 650km round trip tomorrow just to take a look. Fingers crossed! Cheers :)

For what it's worth Ben, coming from a retired diesel mechanic, I reckon you have made the right decision about giving it a big miss.

As Bantam said, he's dreaming.

It could be a good proposition if you are prepared to do an engine rebuild or transplant ........ but at $6gorillas ...... tell him he is dreaming

at $2 gorillas, it might be worth considering ...... IF it is straight.

If you're really keen ask him if you can be there when it is first started cold in the morning, his response should tell all.

No he won't!

It sounds like it is parked on a pile of bullshlt to me...

It's a Landcruiser diesel after all....

Second gear, Handbrake off and let her roll - she'll be a starter.

I didn't realise there was further responses on this thread.

I ended up driving 9 hours (round trip) to have a look at another HJ75 ute on Saturday. I liked it, it was in great condition compared to the earlier one I looked at. One owner (mechanic). I gave the guy a deposit on it, very pleased with how it presents.

Thanks to everyone who took the time to reply, I appreciate it!
