Post by toonfish »

ok its a 1980 swb mq patrol for a good price -sub $1000
a mighty sd 33 diesel 4spd a little rust in window channels and top right windscreen area, still 24 volt system
spare tyre underneath(unfort)
going back to test tomorow as it has been sitting and no fuel or battery (still has water in radiator and oil in motor)
so what should i look for apart from obvious.
my brother is out of town so i cant compresssion test with his tools .
body seems pretty good.260,000 kms, needs sunraysias

while im asking is 24 to 12 volt conversion just alternator and starter changes or just go an 24 to 12 invertor?

80 mod .... its old so rust will be the first thing to look for...

look at these areas...
1/ under the front floormats, specially where the cabmounts are, and look from under the rig aswell.( common)

2/ rear wheel arches, specially the area thats close to ya bum when in the drivers seat. There's an additional panel that corrodes away first.( common)

3/ firewall, just under the rubber strip that the bonnet closes onto. (common)

4/ where the inner guards join the firewall... usually only the passengers side for some unknown reason. ( rare)

5/ front wheel arches, just above where the drivers accelerator foot sits. (rare)

6/ bottom radiator supports... where the radiator bolts on there is a "cup" that joins the inner guard and the front panel... look from underneath (common)

7/ front radiator support panel... where it bolts to the chassis ... visiable from looking through the grill ( common)

8/ front radiator support panel to inner guard... the pretty little curved piece in the corner... ya elbow will probably be resting on it when ya looking at the motor (rare)

9/ gutters ... look from above aswell as underneath ( rare)

10/ under the canopy, specifically within the last foot or so from the back of the rig ( common)

11/ top corners of the windscreen rubber ( rare)

12/ above the glovebox where the door pillar meets the firewall ( rare)

13/ a major one to consider... where the chassis and the gearbox crossmember meet... there's 3 layers of steel here ( internal) and the rust may not be visiable so be prepared to "tap" it with a small hammer, if it dents easily then its prolly rotten from inside. ( rare )

these are the "hidden" rust spots that most people dont see. You can always see the external spots easily IE rear guards, sill panels, bottom of the doors etc etc.

If your still not sure about some of the locations then ASK.... I'll post up some pics for ya !

for mine i just bought a couple of invertors from dick smiths and all of my goodies such as compressor, uhf, stereo, etc. ran off them. As for extra lights 4 sets in addition to the std ones i changed with 24 globes so there was a lot less drain on the batt

remember ASK if ya not sure....

Mechanicls.... Bearings,

1/ front & rear wheel bearings... jack it up, then with ya hands at 12 & 6 oclock on the wheel ...wriggle, you'll "feel" the movement if they are on there way out.

2/ kingpin bearings, jack up one side of the front diff.. 12 & 6 oclock grip again and wriggle firmly... best to have someone do the wriggling so you can see the movement.

Motor...

There's been a few tech disscussions on this so "search" is ya friend here..

basics to look for..

1/ White smoke at inital startup ( cold motor ) with a motor this old there will be some... dont panic, a set of new glowplugs may solve this !... the white smoke should clear within around 10 secs... if its still there after a minute , she's not well !

2/ overheating.... usually due to the radiator being stuffed, again LOOK ! the fins between the cores in the radiator may be gone ! A recored radiator costs around $450.

3/ overheating 2.... injector pump running rich.. a tuneup should fix that, look for excessive clouds of black smoke under acceleration or is there black smoke under normal driving IE @ say 60 kph . ( there will be some black smoke @ 60kph... but it should be "just" visiable). Best way to check this is get someone else to drive it and you follow em.

General appearence....

A 2nd hand car usually sells itself just by appearence, ya look for things like the interior, is it abused, stained, torn, worn out... Seatbelts..are they frayed? this shows how fussy the previous owner was... IE if the rig looks rough then more n likely thats how it was maintained mechanically.

tyres... roadworthy or not
quality of tyres ... cheapies or good name brand, again if they are stuffed cheapies , then more n likely thats the way the rest of the rig was treated.

windscreen and windscreen rubber... is the glass in road worthy condition?, if not then it will need replacing, this then may means that the rubber need replacing too, ... is the rubber "hard" or cracked... if its hard then youll need a new rubber with a new screen, ... cost of a rubber is around the $130 mark... a new screen is around the $150 mark.. + fitting
