OK, sorry to be a little vague, but a friend of mine asked if I could pick up a Distributor for him from the junkyard. his is an older 245 (Round headlites, if that helps), with a b20? in it. I am wondering if any front mounted distributor would work, or do I need to find an older brick to dissect? seems most I see are newer styles, b230's, etc.

thanks,mo

You need more info from your friend.

If it's truly a B20 in the car, it's a 75, and that's a one-year-only engine in a 240. In 1976 they introduced the B21 to North America.

If it's a B20, you need a dist from a 69-up B20E or B20F fuel-injected engine. This should be in any 1800, or 142/144/145E model.

If it's the much more common B21 engine, it'll have Bosch K-Jet fuel injection and you'll need the dist from a 76-81 car. This is what I think you'll find out that you need.

If there's a question, the fender tags should tell you what it is, but really you should get the info off the labels under the hood- assuming they're still readable.

In mid-1982 Volvo introduced a new type of fuel injection, Bosch LH-Jetronic. This was fitted to some 82's but not all. I think the split is January 1, 1982, but do not quote me on that. The engine was still a 2.1 liter (B21). This injection is LH1.0.

In 1983, the engine changed to the 2.3 liter (B23) and the fuel injection version changed, to LH 2.0.

In 1985, the displacement didn't change, but bearings, pistons, and some other details did, and the engine is now known as the B230. The injection version changed to LH 2.2.

Note that all 240 Turbos made from 1981 to 1985 have the B21FT, turbocharged 2.1 liter engine, and retained K-Jet injection. If you need the 76-81 dist, the Turbo one may work for you- check the connector on any that you find.

In 1989, the B230 gained a crank sensor, lost the hall-sensor pickup in the distributor, and the fuel injection became LH 2.4.

In 1991 or so, manual-transmission cars received a further change to LH3.1. My 1992 240 has this. Automatics mostly remained LH2.4, though I have heard of LH3.1 models, never confirmed this in person.

Good luck navigating this. Verify exactly what your friend needs before you go hunting.

In 1975 the B20 used a one-year only distributor with the electronic
ignition system. In order to use any other B20 distributor you must
convert back to points/condensor, etc, which in my estimation is a huge
step backward.

I don't believe this to be the case. I believe the '82 models were sold both ways concurrently. It strikes me that the B21F-LH was indeed introduced in the middle of the model year, but only sold in Calif., or sold everywhere west of the Mississippi.

I know I'm being nitpicky, and it isn't relevant to the topic :)

In any case, having lived most of my Volvo-lovin life in the east and midwest, I've only ever seen ONE B21F-LH car ever. My pals on the West Coast see them all the time.

A good friend of mine and got-it-in-his-blood Volvo gearhead had one of these cars, and other than my own 82 245T, was the only 82 I ever messed around with much.

It was a white 242DL that had been repainted dark green. And at two points in its life, it seized the camshaft. Twice, we were able to clean up the head, clean the transferred aluminum off the cam, and bring it back to life. The third time, I think it got junked!

SOmeone told me oil galleys in the head were a serious problem in this vintage of car- maybe it was a problem just with the new castings without injector holes? Whatever it was, by 1985 it was fixed.

And just how committed was this guy to his peculiar brand of cars? Well, his father owned one of the Volvoville (Long Island, NY dealer) 1800ES convertibles... he had a small fleet of 140's before the 242 came along. A shame they all have to rust, and die.

well, thanks, guys. I guess I am going to have to take a closer look at his car before i go out Junkin. but at least I know a bit more history of theser cars.

So I guess that our 93 940 auto would be a lh 2.4? except that it is regina, so that is a totally different animal, I suppose. I am coriuos, however, because I am toying with the idea of changing to larger injectors, as to run E-85. so I am wanting to learn which vars are equipped with similar injectors, so I can try to scavange a set of larger ones. they go for $4 each at the local self serve scrapper.


well, thanks for the hisrotry lesson, anyway, Mo
