Default Need help: engine stalls (non-subaru)

My car is not a subaru but a 93 Nissan Sentra SE-R automatic.

My friend helped me to install the motor and tranny mounts. During installation, my friend accidently cracked the air box. So, he put some silicone sealant on it to seal it.

Then, I drove the car back. I felt the car lost some power. After more driving, the car toally lost power. The oil light went on a few times. Also, stalled a few times, usually on stop or slow corner. Then, the water temp. raise.

I checked the oil level and looked good. That was my guess because I can't really tell by looking at the dip stick. It looked like way more than the max but I wasn't sure that was the really oil level or just the oil on the side of the tube mark it.

I also heard some weird noise. Sounds like some grinding noise a few times.

Was it my air box?
Was it the mounts?
Was it my oil level? (I'm going to do a oil change in the next few days and see if it helps)

thanks in advance.

It sounds like you have no oil circulating the engine. The reason why I say that is because you wrote:

Oil pressure light came on because the engine lost oil pressure. Water temp rose because the oil wasn't circulating enough. You heard grinding noise because most likely main bearings started to wear out.

When you installed the engine and transmission mounts, how did you support your engine? Did you support it with an engine hoist from top, or did you support it with a floor jack at the oil pan? If at the oil pan, did you use a block of wood to help distribute the weight? If not, the oil pan may have warped to a point where oil pickup tube is now blocked.

If the oil pan is in a good shape, then your engine may have developed an oil circulation problem, not really related to engine mounts installation.

I didn't notice anything wrong with the oil pan but I'll check again tonite when I do the oil change.

Also, the grinding noise and oil light doesn't last long. The oil light came on a few times. Only a few seconds at a time. I think most of the time the engine just died soon after I see the light. Then I can start the engine again and the light is gone.

I heard the grinding noise twice and last for a few seconds. I hope there is no big damage here

Do you have any sugguestion on where to check first for the oil circulation thing?

thanks

I think the surest method to see if the engine has oil circulation is to hook up an oil pressure gauge.

When you change the oil, look for any metal shavings in the old oil. That's one of the indications that something has happened internally.
