Hi 300 lovers,well its a sad head ach day,THE STORY IS

Ive been getting a tapping niose from my engine for the last mounth,first i was told bottom end :hurl:, then told cams,then told valves lifters,now after getting good help on the forum,it seem to be more than liokey valves lifters as the 300 are pron for this prob,so once again i went and got another opp from a former 300 lover,and as soon as he herd the engine he says bottom end :cry:. After speaking to a few more people on the forum,i find there not many ways of telling this unless the engine comes out :cry:.

But wot i was told by paul@swb thanks for the help by the way paul,was to disconect my bbt plug which is at the back of the engine,then turn the car over and if i still hear a nocking niose then its my bottom end is away,so my ? is can any one show me a pic of wot im looking for as im not the greatest when it comes to engines,or any advise would be greatfull.:bow:

Do you mean vtc plug i.e. the plugs for your variable valve? IIRC they are the ones with a white piece of wire attached

Get hold of Paul again as there isn't a BBT plug to my knowledge. Unplugging the wrong item will not help your diagnosis

How louder knocking noise.

I had a small knocking noise which got louder and turned out to be the water pump the bearing failed which finally broke on Friday night and dumped all the water on the floor.

 

Saved the engine though switched off almost immediatly.

 

Took me ages to get home because they had to get a recovery truck with a pan that sits on the floor cause me Z is quite low.

get a garage to put shells in and if still got that noise then its prob from the top and you can put them in with engine in situe

The sound is hard to hear when im driveing,as the sound of the exhaust drowns out any noise,the only time you can hear it is when you accelerate,for about 4-6 seconds ,cant hear it at top end.:confused:

connect a strobe (timing light) up and iff the noise falls in line with the bulb flashes then the chances are its crank related because the camshafts run at a 50% reduction speed

ps..the video you have posted sounds like its true rpm related and that points to the crank not the cam..hth
