The fix is to drop the powertrain, replace the gaskets, drill and tap the block for threaded inserts, etc. My wife's Eldo 120k miles just had it done...$1600 for labor plus parts. I also had the steering rack replaced, a 10 minute job with the powertrain out, otherwise several hours.

That sucks. It more than offsets the easy job a starter replacement is!

Rover 2.6 litre 6 cylinder....without doubt, one of Britains most pathetic efforts at a power plant.
incredibly heavy, incredibly inefficient....an absolute piece of junk.
Land Rover (when British Leyland took them over) got told to use this piece of mechanical buffoonery in their 4WDs as an optional engine....the 2.25 litre Landrover 4 cylinder (which is a pretty good engine) was just about as powerful and a whole lot better design.
Heck...I think I could add quite a few English built engines to this list.....Jag V12's are another nightmare.

I had briefly had a Renault 5 (same as a le car?) with a I think 0.9 liter or 1.1 liter engine and a 4 speed. It often did run right but I enjoyed driving the crap out of it when it did.

I had a Chevy S10 with a 2.8 V6.....worst engine I have ever owned.
I saw someone list the Chevy 305.....I had one of those too....gutless but it ran forever. Had well over 200k on it when we sold it and still ran fine. Had another one with high mileage too.....tried to kill it and couldnt. I didnt change the oil or filter for over 2 years in that one....just added about half a quart every week because it leaked. Then I drove it to work and back every day with the oil level so low that every curve I hit the oil pressure would drop to 0....for over a week. Ended up trading that car to a guy who drove it for over a year before he wrecked it.

Put a blower on the 425 (or install a 472/500) and put a blower on that. Paint it all black, install a 3.55 axle and go hunting for musclecars.

Hot Rod, or one of the other big magazines did a build up on a 255, because that year ford decided to quit making the 302.......

I respectfully disagree about the GM 2.8 V6. Gutless wonder (what wasn't in the early to mid 80s?), but durable.

Agreed.
Agreed.
Agreed.
And - agreed.

ALL of the small displacement V8s that were brought out as an under-engineered knee-jerk reaction to the oil embargos were GUTLESS!

Special mention and a gold star for Ford's unmitigated disaster of the late 70's - early 80's - the Variable Venturi carburetor. What a POS!

My dad bought an 86 GMC S 15 new with the tech 4 and a 4 speed. It had the roller cam. No options. We re-ringed it at 150,000 miles when it broke a couple of head bolts, and he parted out the truck when it spun a bearing at just over 400,000 miles. Gutless but long-lasting.

I briefly owned an 80 Monza with the iron puke and a 4 speed. That car was so gutless my buddy's late 80s/early 90s hyundai kicked its butt...

I would nominate the 2.0 used in the Dodge Neon for one of the worst (at least the earlier ones). They all blew head gaskets at about 30,000 miles.

We had a 1979 LTD with the 302 and that VV disaster. It was a pig but at least it got terrible gas mileage.

Anyone ever test the coolant with a voltmeter ? You'd be surprised at the readings.

QUAD 4 in all of it's variants.

3.0 Mitsu ranks right up there also.

Yea, but 6.9 & 7.3s suffer in the back from cavitation. With diesel being so high I'm tempted to drop the 30,xxx mile original 304 back in the Loadstar -

The 2.8 and 3.1 in FWD cars had aluminum heads. The intake gaskets were poorly designed, the gaskets would leak coolant into the crank case. You have to pull all the intake crap off, then ALSO take off the push rods and rocker arms. THe intake gaskets also served as push rod guide plates. The parts are only around $60.00, labor around $500.00. unless you DIY it, as I did for a former woman friend.....I need find out the condition of these women's cars, before we go to the movies for the first time...LOL

The 2.8/3.1 family doesn't really belong in here in my opinion, I worked in a buick dealership in the early mid 80s and we really had no problems with them. I owned a 91 Z24 3.1 that I bought 110,000 on it for $200 that I drove over 200,000 miles with mediocre service and except for coil packs and a control module, crank sensor, plug wires and plugs, and a water pump it was pretty much trouuble free. I scrapped it for close to $400 so it didn't owe me a cent. The timing gear finally sheared the nylon off and it bent some valves so I junked it. I really wonder how many more miles it would have gone if I had fixed it and continued to drive it.

I agree with Sirottica. I had plenty of customers in the early-mid '90's that had the 2.8 Cavaliers and the 3.1's as well, and these cars went well over 200k with regular oil changes and little else. One lady customer had a Z24 Cavalier with about 300k on it, and it ran extremely well.

Agreed.

Most weren't TOO bad. Intake gaskets ALWAYS failed, but 90% of the time we caught them before coolant leaked into the oil.

NEVER a powerhouse, but quite sturdy all in all.
