Thread: 300TDI Clatter

Thanks Marty, the curious thing is that the "click" occurs alternately with no.1 exhaust, and no.3 inlet, at exactly the same point of rotation of the crankshaft. I have the cover off the injection distributor, so will check if it "jumps"at the same point. That would lead me to assume the belt is jumping as well, and suspect the driving gear on the crankshaft "has issues" with the woodruff key. Hmmmmm.............

Hi LR1953

Beside those checks the other's have suggested, I would also do a check on the vacuum pump.

The gasket between the vacuum pump and the block can crush over time causing a few problems, fit a new thick gasket or a couple of thin gaskets and try that.

To find and locate the source of a noise, I would use a poor man's stethoscope, use a length of plastic tube or garden hose up to your ear and poke the other end around the running engine, you will soon find where the noise is the loudest.

The big-ends in my 300Tdi started "rattling" at high revs, seemed strange to me no knocking at lower revs. The hard-facing was just starting to break down in a few spots. Apparently a common issue at 150k-200k on these motors.

have you checked the fuel filter?

Hi All, just over a week ago I posted re "300TDI Clatter". I now have the answer (cause) and hopefully the extent of the results. Pulled the timing case cover off and discovered that the bolt holding the drive gear to the front of the camshaft had worked loose. This allowed the cam a small amount of uncontrolled rotation, ie was moving in and out of synch with crankshaft and injector pump. See attached pictures of worn/damaged boss still bolted to the pressed steel gear and the replacement boss. Wear is apparent on both front and back of the boss. The pin (not shown) which locates the boss on the front of the camshaft appears OK. Pushrods all look straight and I'm told they bend before valve stems in this kind of situation. So....... a new cambelt kit and all should be good!

Threads merged.

If you manage to resolve an issue, just carry on from the original thread. That way the symptom, cause & solution are all in one place.

I guess we won't be seeing you in the isuzu section asking about replacing a blown engine then?

these belts are the reason I have not been able to enjoy my LR's; such a bloody stooopid idea to put a lacky band in control of the most important job in the engine. Also the reason I was bluntly insisting you check it first; despite assurances otherwise, I just do not trust them at any Km mark, though not entirely sure why that is considering I've never experienced one snapping.

i suppose they are like the damocles sword of landrover ownership.

To be fair, it wasn't a belt issue with the car. It was a loose bolt on the camshaft gear - the same bolt that secures a chain driven gear.
