I have a 1994 Ram 1500 with a 5.2L v8, and it looks like I may have a oil leak developing at the front of the intake manifold near the right corner. I'm just wondering if oil flows through the intake manifold there or is the leak likely coming from elsewhere?

 

No oil thru the manifold. Is your PCV system working properly?

Might be running down from the valve cover........

 

I'd guess it's leaking out the valve cover gasket, or from the PCV or breather on your valve cover as mentioned above.

 

I had the same problem, thats what led me to do my plenum gasket. It was the intake manifold gasket in the front. This is what mine looked like before I tore it down



all finished havent had any problems since

 

wow...... ugly mess.....

 

Nice job on the gasket replacement and intake cleanup... I just did a top end on a 360 1995.... I have a question about the sensor locate just to the right of the water return. Can you identify it for me. A friend who owned the vehicle, did the dis-assembly four year ago. I had to just rely on instinct as to reconnecting every thing, as I had never worked on this year engine before.
I did not see any connection from the sensor, except there is on connector just above at the crossover harness. There did not seem to be anything it fed, but was directly above.
Any assistance you can offer is greatly appreciated.

On the older trucks, there are two temp sensors. The one on the passenger side of the thermo housing is a single wire connector, for the gauge in the dash, the one on the drivers side is a two wire connector for the PCM.

 

Thanks for the info. The passenger side sensor is connected, and my gauge is reading properly. The center sensor is not wired. Would this cause the pcm to produce a code that says the temp sensor is out of range? And possibly cause the engine to hesitate and quit when I go from park to drive. I have particular problems keeping the engine running at idle.
Thanks

Yep. If the PCM isn't being clued in as to engine temp, it has no idea of how much gas to add..... so, it defaults to some limp-home tables, which, obviously, aren't very good.

Need to find the connector for that sensor. Otherwise, the truck will never be really driveable.

 

Just hoping some one can suggest a source for the two wire pigtail that connects the water temp sensor to the power control module harness connection. No luck at the dealer, at the parts yards or the salvage yards.
If I had the plug ends I could solder up the leads.
Thanks
