This engine is well known for cracking cylinder heads and causing that.

what all needs to be replaced, if that is the case? how long would be estimated time to complete work?

It's a major repair at considerable expense, $1000 or more. The cylinder head will have to be replaced and all that oil has to be cleaned out somehow.

I haven't examined your car so this is nothing but a suggestion that should be checked. Don't plan a repair around my guess.

it isn't cracked. there's an oil cooler that the coolant runs through to cool the engine. it can leak. the oil would leak into the coolant because it's much higher pressure, but the coolant wouldn't go into the oil. sorry i didn't reply sooner

We are all glad you didn't reply sooner as you don't know diddle and shouldn't post on a finished thead. Oil/coolant can leak anywhich way the opportunity area allows. You thing YOU know what's going on with this one?

Yeah, he thinks he's real smart. This engine doesn't have a cooler.

Here's a TSB on the head problem. They even extended the warranty for this.


Bulletin No.: 99-P-01
Date: January 04, 2005
SPECIAL POLICY Subject:
Replacement of Cracked Cylinder Heads Models:
1994-1996 Saturn S-Series Vehicles with Single Overhead Cam (SOHC) Engines (1994: RPO LKO, 1995-1996: RPO L24) Attention: All Saturn Retailers and Authorized Service Providers in the United States and Canada
Condition
Certain Saturn vehicles equipped with 1.9L SOHC engines may develop a crack internal to the cylinder head. Early evidence of this would be abnormal discoloration within the coolant reservoir, and/or the engine may run hot.
Special Policy Adjustment
This Special Policy provides cylinder head coverage for a period of six years from the date the vehicle was originally placed in service, or 100,000 miles (160,000 km), whichever occurs first. The policy covers both the original owner, and any subsequent owners for the six-year/100,000 mile (160,000km) duration. The qualifying repairs will be made at no charge to the customer.
Vehicles Involved
All 1994-1996 Saturn S-Series vehicles equipped with 1.9L SOHC engines.
Parts Information
Parts required to perform a cylinder head replacement are to be obtained from Technical Information Bulletin 96-T-65B.
Service Procedure
When replacement of the cylinder head is required, refer to the service procedure as outlined in Technical Information Bulletin 96-T-65B.
Customer Notification
Customers will be notified of this special policy on their vehicles by Saturn Corporation via first class mail.
Customer Reimbursement
Customers with claims for previously paid repairs to replace the cylinder head for the subject condition are requested to contact their Saturn Retailer or the Saturn Customer Assistance Center to arrange for reimbursement. Repairs must have been performed within six years of the date the vehicle was originally placed in service, or 100,000 miles (160,000 km), whichever occurs first. If the repair was performed at a non-Saturn facility, customers will need to provide the original paid receipt or invoice verifying the repair, and proof of ownership of the vehicle at the time of repair.
