I have a 1991 Cadillac Brougham, the old rear-wheel-drive model. The car was sitting for a long time, and it has a Chevy 305 with bad valve seals. Lesson: beware of low-low-mileage cars.

It smokes badly on startup after sitting and burns a good bit of oil — about one quart every 250 miles. I’ve driven it as-is for a while, but the day is coming when I’ll need to do something about it.

I was told that the heads would need to be replaced to the tune of about $800. I am thinking for that kind of money I can go ahead and swap out the 305 for an LS. I was quoted about $2,750 for a 5.3-liter junkyard LS swap and $3,750 for a 6.0-liter junkyard LS swap, start to finish.

Hello Sajeev,

This is my second time writing in about my Oldsmobile. I solved the cooling problem with a mechanical fan, however now I am having another problem. As you may recall I swapped in a ZZ4 GM Performance 350 CI motor, and now it will “diesel” for awhile after I shut it off. It only does this after it has had a chance to warm up. Do you have any ideas for fixing this?

Thanks,

Luxury roadsters have always been niche vehicles. With the economic implosion over the last decade, that niche has become even smaller. Last year the Mercedes SLK and BMW Z4 each sold less than 3,500 units on our shores, down from over 10,000 each back in 2006 and Canadian sales are roughly a tenth of that. While Mercedes is likely crying in their delicious geflügelsuppe, roadster shoppers benefit by being able to drive one of the most exclusive Mercedes models available on our shores. While the last model awkwardly aped the unholy union of a Mercdes F1 car and a bottlenose dolphin, the new model sells itself with sexy new sheet metal, 29 MPG on the highway and a $54,800 base price.
