need help with finding out about the noise coming from my engine. I had the intake manifiold gasket replacet and 2 day after my oil pressure droped, changed the oil pump but there is still a noise in the engine. One mechanic said that I have bad lifters , other one said "no, that's deep in the engine , not lifters". Went back to the guy and he said he's sure that the lifterds are bad and he's willing to change them and don't charge me if the sound its still there. Just hope I do not have to replace the engine like one mechanic said
