Ok here is my question would a crank position sensor possibly make my engine knock if it has been replaced? Sorry for long post here goes my nightmare story.

I purchased a 97 rover with 120k on the clock, it ran beautifuly for about 2.5 days, after which I had to replace tranny as it was sticking in gear without upshifting or downshifting. The nightmare began it was towed to have tranny rebuilt with was fine on the lift but I was told my transfer case was noisy it had to be replaced as it was not safe to drive it was only engaged in low drive. I said it was ok i would replace at a later time, took truck off lift and began to drive, it hesitated terrible had no power at all. I figured the tranfer case was the culprit. So the transfer case was replaced, then after that same tranny shop informs me truck will not start. I need a new starter and alternator as it will not hold charge or even start. It seemed crazy truck was fine for the 2.5 days before tranny issues, they managed to start but will not run fine the have replaced wires and plugs it idles beautifuly but as soon as gas was given it would stutter. So the managed to figure out it was my crank position sensor after pulling codes it also had some wiring that was damaged( from them I assume). So after crank position sensor was changed truck developed a tick only noticeable if gas was let off. Truck was picked up no dummy lights or anything ran like a charm other than slight tick drove home 13 miles.

Next day it would not start, so found out battery was bad replaced, starter and alternator was replaced as well. After finding out the hard way to replace alternator before starter (burned out my starter) had everything buttoned up cranked only to find my oil dummy light on with a HORRENDOUS KNOCKING from engine. I might be ******** but i swear the cranking sound sounds as if timing is off.


Anyone have any ideas as to what it could possibly be if not crank sensor????????




Thanks in advance

Hate to say this, but it sounds more like the oil pick up tube is clogged bad... drop the oil pan, clean the pan and the oil pick up tube and all should be fine.

It sounds to me like the previous owner didn't take very good care of you current Disco.

I forgot to mention dropping pan and checking oil pickup tube as mentioned here. It was not clogged did have alot of gunk on the bottom so it was cleaned up pressure washed and put back together with fingures crossed but still same knock and dummy light..

Could be a bad oil pump, or a bolt coming loose from the recent transmission repair.

If you have a mechanics stethoscope you should be able to find the source of the noise fairly fast.

If you don't have a mechanics stethoscope you can use a broom stick or a piece of garden hose. I know it sounds like BS but try it you will be surprised how well the stick works. Joe

Ok, I'm intrigued how would I use the broomstick? I can see for the garden hose but not broomstick.



Thanks

LOL. OK, it is as simple as sticking it to your ear and pressing the other end of it to the area you want to listen to. It has to be a solid stick, broom stick, painters stick, walking stick, pretty much anything solid, It is so clear that you can listen to each individual valve through the valve cover and able to figure out if it is an exhaust valve or a fuel valve that is making noise, but if your trying to hear vacuum leaks you have to use a hose. Everyone laughs when they see it, then they spend an hour doing it. Joe

I would normally use a very long screwdriver if I don't have a stethoscope handy.
