Hi

If it is an automatic model, check the converter fixing bolts are not loose !

Good Luck !

John.

3.1L has rod knock. I have 20yrs of auto mechanic and built a few engines, but retired now.


If the knocking is from the bottom of the engine, it may be the big end bearings have worn.
Replace them or not? Difficult question.

Replacing the big end (crankshaft/piston rod) bearings may stop the knocking/rumble noise. It depends on the crankshaft..

If the crankshaft has worn oval on its journals, fitting new bearings is unlikely to achieve anything as the bearings may break up due to the oval of the crankshaft. Removing the crankshaft and checking the journals for ovality/regrinding if necessary isn't a 5 minute job.

You say you have good oil pressure. That's a positive.

Personally, in your situation, I would try an engine oil additive that's designed to eliminate knock provided the main bearings haven't worn down to base metal. It's the cheapest option.

Failing that - and again, personally - I would remove the oil pan and fit new big end bearings in the hope that it would work.

The next step, if that doesn't work - would be to remove the crankshaft and have it reground and fit oversize bearings. Or get a 2nd hand engine...

You say the car was given to you for free .. you have nothing to lose. Try an additive first.. molyslip/molybdenum or whatever...

Good luck ...

My nissan murano locked up going down road. Engin was running fine it started a little knock before it locked up 2003 model. Thanks. Can a starter cause this problem


Sounds like you ran out of oil and have seized the big end bearings. The knock before they seize. Could also be an inoperative oil pump.

Get it towed to a garage.

MY ENGINE HAS A KNOCK TO IT


you need to establish if its bottom end or top end. if bottom end big end bearings have gone then its a big job ( easier to replace engine ) and if its top end ( cam ) then its a mornings job. big difference. hope this helps

The engine on my 2001 nissan altima is making a loud knocking noise.. 1st they said it could be the fuel injectors, someone else said it could be the oxygen sensors.. someone else said i needed another...


My advice would be to take it to a local garage and offer him £5 to listen to the engine and to tell you what he thinks it is but, bearing in mind it is a 10 year old engine and, at a guess has done considerable mileage, don't be surprised if he tells you that the big ends are gone. At the very least you lose £5 at worst you may need a new engine.

A good mechanic should be able to put an ear to the engine and tell straightaway if it is a major job.

I have a loud knocking noise coming from my 3.5l engine on my 2000 intrigue. i am wanting to know what the problem is so i can decide to fix it or not. thanks


a loud knocking normally indicates big end bearings,(about 1/4 engine speed)not a big job but,an engine rebore/rebuild is normally the way to go,its cheaper in the long run.....
