Thread: HELP! Noisy TDi 300

Ooooo......found a bent push rod on #8!
Not alot but bent just the same!
Top of tappet slide also slightly damaged by pushod (not seated properly).
Am going to replace all the pushrods and see what happens.
Rocker gear was fine!

thank god you were right, bet you thought you were going nuts lol
how much to get her back on the starting blocks mate ?

Just gaping tappets now!

Will know if fixed in 30 mins!

fingers crossed!

That'll do it Cliffy, bent pushrods will make tappet adjustment impossible.

I'll wager you will have a nice quite Tdi after this

Out of interest which valve cap was missing? was it #8?

I have a similar noise in my Defender that I can't seem to locate, mine was without #1 valve cap for a while and I'm just wondering whether my pushrod has done the same thing

Only discovered what it was a couple of weeks ago - the rubber mounts of the air fliter assy perish and break and the ticking the whole thing makes sounds just like noisy tappets. Took the lot out, 2 broken, replaced all four, now sounds like a healthy 300 tdi again. Worth a check!

Hopefully this is the problem with mine. I noticed the other day my rubber mounts were buggered. I have another set coming tomorrow hopefully

Does the clatter happen all the time?

My TDi makes a horrible racket at idle or low speed, but seems to go away at higher speed. It happened after I had a new cam belt put on, then the mechanic said it was normal diesel knock. Problem is, it comes and goes, and wasn't being very loud at the mechanics, but seems to get worse when warm.

Well.......new push rods and....................exactly the same!
Not one bit quieter!! But have just discovered the vac pump cover loose!
Something else to replace but not the problem i think.
It's a loud tap-tap-tap that appears to come from the top of the motor. Seems to be on only one cylinder. Got me beat!
Only thing left to do now is either pull the head off and or rip the whole donk out and strip.
It's very hard to pick where it's comeing from but it's load inside the cab.
I will keep you all posted.
(I think it's not the vac pump as the noise does not come from near it)

What a job getting that off!!!
Got an eye full of mud. Pump off, noise still there!
Pump cover seemed loose but now tight (maybe cause not in operation).
AAAAAaaaaggghhhhhh!!!!!
Gonna have a good listen with the stethascope and see if I can pin point exactly where this noise is from.
Man this is doing my head in!
