answer and you get a cookie....

I need the cylinder head specifications for an S-series 1.9 DOHC engine. Car model and year are unknown as is the casting number. The head does have " A 266 " stamped on it and the blcok has " B 326 " and " 21000950 " on it, can anybody translate this into something relatively useful? Ok for the head specs I need: Valve Angle, Vavle Spring Installed Height, Valve Stem Diameter, Valve Guide Clearance and Valve Head Diameter. If theres any other info that would be useful hit me up and Ill try to get a hold of it. Thanks for your help.

i think i want more than a cookie for that answer... i'll do some research for ya

What year is the vehicle?

Yeah, a cookie isn't going to recoop the cost of that Saturn mechanic's manual...

Hah, yea I know this isn't the easiest information to obtain. I'm rebuilding this engine for a class and it's required to know these specs. Everyones help is greatly appreciated. and no sorry, but no I dont know the year of the car it came from.

what does the cam cover look like? is it aluminum or composite?

Looks to be aluminum

ok so its an earlier model 91-97 probably... i think they changed it in 98. someone correct me if i'm wrong but that should help on finding the specs... that takes out at least 5 years...

Thanks carguy83!! Thats a pretty big step in finding out what I need to know. Can anybody find the head specs for this engine?

have you thought about calling a saturn dealership?

IF it is the alumium valve cover, then its 91-95. to confirm this, there should be two coolent temp sensors by the upper radiator hose. the engine in this pic only has one, under the EGR, the second sensor would be above the first sensor.

specs according to haynes repair manual(for 91-97/98 DOHC, depending on spec):

Valve Face Angle- 44.5 - 45.5 degrees
Valve Spring Free Length- 1.61 In
Vavle Spring Pressure- 163-180Lb (157lb service limit) @ 0.984 In; 66-77Lb (63lb service limit) @ 1.34 In
Valve Stem Diameter- Intake - 0.2736-0.274in(0.273 service limit); exhaust - 0.2726-0.2736in (0.272 service limit)
Valve Stem to Guide Clearance- Intake - 0.001-0.0025in(0.004 service limit); exhaust - 0.0015-0.0032in(0.005 service limit)
Valve Margin width- Intake - 0.0378-0.0496in(0.035 service limit); exhaust - 0.0441-0.0559in (0.039 service limit)
Valve Seat width- Intake - 0.0394-0.0512in(0.0653 service limit); exhaust - 0.0512-0.0630in (0.0756 service limit)
