Question SOHC years to avoid?

I'm looking at getting myself another S-series but don't want to have to worry about the cracked head issue. What are the years that had the problems with the heads cracking? Also, does anyone know offhand what year did the SOHC go to 100 HP from 85 HP?

Thanks,

Ken

SOHC cars were TBI from 91-94 and multiport from 95-2002

tbi=85hp, multiport =100hp

cracked heads could happen (seen them happen) up to 99 model year. however, this was only in a small persentage of cars...

personally, i would avoid all SOHC cars

the DOHC gets almost exactly the same gas mileage and it is ALOT faster

ive never heard of head cracking being a problem on any saturn

Oh yes, there was a special adjustment policy on SOHC head gaskets and heads.

Post on the tech board for the exact years. Saturn had a special 7 year, 100K adjustment policy on this if I recall correctly.

It was a "warranty extension", not a recall. It was for 6years 100000mi (160000k in Canada) for 94 through 96 model years

Interesting. I had thought that '96 and perhaps '97 had the issues with some heads cracking. But I have to agree with Turd Fergusen that probably DOHC is the way to go regardless. I do want to get a stick, though. I have a friend who deals in used cars and he deals almost exclusively in Saturns. He seems to always be able to find Saturns for unheard of prices.

I've had great luck with all my SOHC's. I don't think the gas mileage is the same unless you're really flogging it around -- then either engine would get lousy mileage. My lifetime gas mileage for the SOHC's I've commuted with have all been right around 40 mpg.

Just curious though, why are/were the Saturn OLAP S Series cars all SOHC's? Are the SOHC more durable?

I also thought someone once indicated the SOHC timing chain was more likely to last longer since it only had to operate a single cam shaft.

the Saturn One Lap of America s-series coupes were DOHC aka "twin cam". Saturn called the coupe an "SC1" so it would fit into the economy class for cars under $15,000. really it was an SC1 with an SC2 engine in it. wink wink nudge nudge.
