What to look for when buying a 245 diesel[740-760/85] posted by Michael on

I have an 84 B23F FI and am seeking advice in purchasing an 84 240 wagon diesel with 115K mi. on it. Are there any big problems with the diesels? Reliability? Ease of repair? Maintenance? I would appreciate any feedback

Look back for the last week or two, and you'll see a similar question posted. Also check the archives.
Reliabillity: Pretty good
Ease of repair: PITA
Maintenance: Mostly, a breeze.
You'll find yourself sticking a foot out the door to help peddle the car to make it up some hills, but for 78 hp, what whould you expect?

Here's my 2-cents worth on your question.

When I was considering buying my car, I took it to Carl. (This guy has forgotten more than a lot of us will ever know about cars, engines, etc., etc.) He told me that if I didn't get at least 300,000 miles out of the engine, I got a lemon.

My own experience with the D24 leads me to tell you to look for/do the following before you buy:

1) Open the hood and make sure it has a block heater. (Don't know where you live, but it doesn't matter.) If it doesn't, I'd find out how much the Volvo place charges (P&L) and knock that much off the price.

2) Look for fuel and oil leaks. These are not good. On a diesel these are easy to spot - look for the dirtiest spots. Locate and identify all leaks!

3) Check the air filter for oil on the element. If it's there, you need to be sure WHY it's there before buying. I can't think of a case where this is good!

4) Check the oil level and then drive the car AT LEAST 50 MILES at one time. Listen to the engine "noise" before and after. If it hasn't changed, you may have a keeper. If it has, you may be about to buy a problem, because someone may have put something in it to quiet it down. Diesels are noisier than gas rigs, just comes with the territory.

5) When you drive it, get it up to temp, put it into third (manual trans.) and put the accelerator to the firewall. Hold it there for 20-30 seconds. Look into your rearview mirror. If you have blanked out the entire landscape behind you, you know that the car has not been driven hard enough to blow out the soot from the exhaust system. Driving a diesel correctly is a lot different from driving a gas rig "correctly". You can and should drive them "harder", but not to extreme. Once the exhaust clears up, put it into 4th and run it at about 3200 rpm. You should not detect anything like the "miss" you'd get from a spark plug in a gas engine. If you do detect a miss, especially after blowing it out, you'd better beware.

6) Make sure the car has the CORRECT SIZE BATTERY in it! I run only the Interstate MB-8850. With the compression that you work against starting the car, you MUST have the best rated battery you can buy. They aren't cheap, but starting this engine will grind a lesser battery down in no time.

7) Check all around the head gasket for leaks of combustion products. I would suggest that before you take it on the 50+ mile drive, take it to the carwash, let it cool off, wash the engine AND engine compartment stem to stern and look 'er over real good. Once you have driven it the 50+ miles (the more the better), pop the hood and look it over real good again. Head gasket, injector pump, injectors, power stearing unit, "PCV valve" port on top of valve cover, all around valve cover gasket, just everywhere. There should be NO LEAKS anywhere!

8) Ask for proof of the fuel mileage (mpg). If it doesn't get between 30 and 40, you may need to find out why. Doesn't mean anything's necessarily wrong, but could be. Could be only the air/fuel mixture needs adjusting and that's it. BUT, if it is traced to the injector pump or bad injectors, you are looking at quite a bit of money. A new injector pump could run to $4700 or more, while a rebuilt one will lighten your billfold by around $1700 and up.

9) If the car has a needle-type oil pressure guage, make sure it works. If it doesn't have one, I'd sure consider putting one in. Ask what kind of oil has been used in it and how often it has been changed. Ask for the maintenance records and look them over carefully (at home where you can concentrate on what you're reading).

10) Look for a belly pan. If shain't got one, get one.

11) Check the rear license plate lamps when you turn the headlights on and the rear wiper. If they don't both work, you may have a wiring harness broken. 245's are famous for breaking rear wiring harnesses.

12) Check condition of cam and timing belts. This is pretty easy.

13) I'd also check the fuel filter. Get a small plastic cup (like the kind they give you on airlines), put it under the finger wheel on the bottom of the filter. Loosen it about half a turn, then loosen the bleed nut on top with a straight screwdriver for about 3 seconds. Close the valve and the finger wheel and hold your cup up to the light. If you see water in the bottom of the cup, you may have damaged injectors (they don't like water!), which may also be reflected in lower mileage and excessive tailpipe smoke. If there is any other "trash" in cup, be leary.

That's about all I'd check, but that's enough. If everything pans out okay, you should consider buying it, in my opinion. I've had mine for 14 years and like it pretty darn good. I'd buy another one in a minute if I could. I plan to replace the engine in this one with another diesel when this one plays out.

If you have other questions, fire away. I'll help you any way I can. I also agree with Ed's assessment, just for the record - 'cept I don't know what PITA means! :) Have a good'un! (If I misspelled anything, I'm sorry, but it's 0100 here and I don't plan to proof this before posting. Normally I would, but not tonight!) --
