"Low Engine Oil Pressure" Do I really need a new engine?
So i took my Jeep into the shop today to get it looked over because my oil
pressure drops really low when i have it in idle. (which i know is normal but it
was really low so i got it looked at) The mechanic basically told me ill need a
new engine "soon, or it could last me 10 years". it hasnt started knocking yet
and i dont want to have to buy a new engine. Suggestions?
Low oil pressure, if it isn't the oil pump, is usually caused by worn engine bearings, you can try using a heavier weight oil as the outside temps rise but this is only treating a symptom not the real problem.
What tennisshoes said.
I'm just baffled a little by how the only fix is to get an entire new engine
You don't have too, you can have yours rebuilt, but you won't get the warranty that you would if you had it replaced.
Would that be cheaper than replacing the whole thing?
There in lies the rub, usually it does not, cause there is more labor involved and your rig is down a lot longer, then of course there is always the unforeseen complication that comes along and really set it all back, like a pin hole in the block or it needs line bored, something. That's why most places just replace the unit anymore, that way you and the installer are covered if something happens to the replacement within the warranty period, in the long run it is actually cheaper to replace the engine if your having to done at a shop.
Thanks a lot, you've given me some comfort in my engine problems
As it isn't knocking yet, I would run like a racing oil in it say a 20/50 during the summer and drop back to a 10/40 or a 10/30 if that is too heavy for winter and give it time to warm up when it is cold. Or you could use power punch oil additive during each oil change, you need to try and keep the pressures up so the top end of the engine gets lube, the lifters will start clicking when they loose oil pressure, so be aware of that.

Try a high volume oil pump first
you can test your oil pump.remove it and test it for wear
