SOURCE: my isuzu dmax oil pan

In order for that dent to have any real effect upon oil delivery, the dent would need to be perfectly flat up against the oil pump pickup. Chances are it isn't. The pickup in most pans is located a bit above the pan bottom to lessen the chance of ingesting any contaminants (sand, grit, hard carbon etc). With the clearance diminished, chances of that are greater.
While only oil pressure is measured, volume is also important. With the pan that close to the pickup, pressure probably won't be a problem but you may loose some volume (impossible to tell how much).
When I put together a fresh engine, I like to see pressure of about 40psi or better. As an engine wears, engineers claim that anything above 15psi is OK...I use a higher number of 25psi (at idle) as a minimum "safe" limit. Anything below that, you know you have a problem and it's wise to find it early and fix it. (Pumps rarely fail...most low pressure problems can be traced to engine bearing wear, resulting in bleed off past the bearings)
As for your pan: If the pan is bent, and you have it off the engine, why not hammer the bend out a little? or, better yet, get another pan from a scrapyard and replace it entirely?
If you have not removed it, there's no real way of measuring and what you are seeing may not be the whole story...pickup clearance may be greater elsewhere. In that case, just continue doing regular service and save pan replacement for a day when you have time to do it.

Broken timing belt


Make sure motor is at TDC. Belts, hoses and radiator need to come out. Pulleys too. Drop front of oil pan, then remove front timing cover.
Install new belt, button 'er back up and check timing. About a six hour job, twice as long the first time.

I have a 91 Isuzu pick up manual transmission 5 speed that makes a high whining noise in 1st 2nd and 5th gear. What could this be?


Have you checked the level of gear oil in the transmission? Remove the fill plug and see if oil is up to the hole.

I HAVE A ISUZU 4JA1 ENGINE WHEN IT IS RUNNING ON LONG RUNS THE OIL COMES OUT FROM THE DIP STICK WHAT WOULD BE THE PROBLEM WITH THE ENGINE


If you are NOT overfilling the oil then it's a clogged oil pump. Drop the oil pan (have a new gasket set ready), pull the pump and strainer and clean with solvent (acetone), and re-install.

Removing the oil pan from a 1994 vw jetta


you have to remove the oil pan without the gasket because the gasket is attached to your oil pan baffle and that can't be removed until you unbolt your oil pump. i pried the **** out of mine until i realized the gasket couldn't come with it. no haynes manual will explain it as simple as it could be, i hate those books
