#1065 of 1218 1998 Catera no compression #4 by sskl Jun 01, 2009 (6:14 am)
104000 miles in mint condition except no compression on #4 (if I'm right) driver's side. Can hear compressed leak from crankcase from dipstick tube per engine cycle. I am assuming I have a hole in the #4 piston or ring problem. Valves are moving with cam but can hear a slight tick-tick. I am open to thoughts and suggestions before I teardown engine. Love the car and will solve this problem. Thanks; Dave Replies to this message: Mr_Shiftright (Jun 01, 2009 6:17 am) sskl (Jun 01, 2009 9:50 am) Mr_Shiftright (Jun 01, 2009 11:06 am) and 1 more...

Replying to: sskl (Jun 01, 2009 6:14 am) I'd do a cylinder leakdown test on that cylinder to confirm. I don't think the piston is holed--you wouldn't hear anything in that case. (hole too big). Maybe you broke a compression ring? Was the car pinging like crazy? Did you have a really bad overheat?

Replying to: Mr_Shiftright (Jun 01, 2009 6:17 am) Thanks; Will do, Started car this AM and got up to 45 PSI dry. Give me a correct leakdown process. Have done it some time ago with oil and air compressor on other cars but need reminding of proper sequence.

Replying to: sskl (Jun 01, 2009 9:50 am) Well you'd need the proper fitting and gauges.   Wanna build your own?   http://www.vmaxoutlaw.com/tech/leakdown_tester.htm Replies to this message: sskl (Jun 01, 2009 11:28 am)

#1070 of 1218 Oil in 97 cateras coolant. by 2mahc123 Jun 03, 2009 (7:05 pm)
I have a 97 Catera and the coolant got mix with engine oil but the engine oil does not have any coolant on it. Do anybody know why is this happening and how to fix the problem, To me it seems like the head gasket must have a leek but the strange part is that the car is running perfectly, and besides the low oil level light that came on, (because of the oil that was sucked into the coolant system) there is no other sign of malfunction. I will appreciate any comments. Replies to this message: Mr_Shiftright (Jun 03, 2009 8:37 pm) phil2400 (Jun 04, 2009 4:46 am)

Replying to: 2mahc123 (Jun 03, 2009 7:05 pm) Check your transmission fluid. Could be a leak in the transmission oil cooler, which is attached to the right end tank of your radiator.

Replying to: 2mahc123 (Jun 03, 2009 7:05 pm) With motor oil disappearing from the engine and showing up in the coolant means your oil cooler is leaking. This engine has an oil cooler located inbetween the cylinder banks underneath the intake manifold in a coolant bath. If the cooler leaks, it pumps motor oil straight into the coolant. Cadillac has a kit to fix this with everything you need to get to the cooler and replace it. A friend of mine found it on-line for a shade over $400.
#1073 of 1218 98 Cadillac Catera needs new ignition switch. Please Help by hinojosajc Jun 04, 2009 (6:56 pm)
I have a 98 Cadillac Catera. At first it would crank but does not start/fire. I change the ignition coil, the stark plugs, the crank sensor, and the ECU. After giving up I took a look at the ignition switch. If I hold the ignition switch the car will start and then die.. I bought a new ignition switch but don't know where to start.. Please help...
