tappet noise was......

[murran]

had a noticeable tappet noise on mine for the last few weeks getiing much worse in the last few days up to wednesday when i started taking it to bits to find out what it was.
left the head on took the rad out etc. and got the shaft out thru the front.

bearing in mind i have refurbed the head on my 325i engine before i stuck it in my 320i touring..... and all the rockers were minty mint 10 months ago....... how does just 1 of them get like this???



a good one.....


the good one next to the fubar one.....


its marked the cam lobe a bit too.
ive got a s/h rocker off town325i, tho it is worn. its not terrible
thing is im looking to swap the car in the next couple of months for an e28 m535i off a chap on retro rides forum.

what would you do??

[johnny_boymk1]

replace, rebuild and get rid. Good luck

[Bob_S]

replace it, I'd say there was too much pressure on that rocker causing it to wear, were your valve tolerances good? I heard to have them slightly loose was better my 2.7 used to tap all the time but never had any issues

[murran]

i set them all properly with my feelers. who knows!
anyway built it back up this morning changed the oil and filter...... its back to sounding lovely again.
gave it a good thrash round the block after to remind me why i love my 325i.

Looks like the hardened section has fallen off (or was made of chees), are you sure its not rattling around in there still ?

[murran]

there was a couple of little metaly bits came out with the oil.
anyway if there are more bits in the sump its not something i can be bothered taking it off (on my back in the cold and wet) for!

[gaszman]

did it sound like mine ???????



if so maybe its also a quick fix have a spare head to go on ?????

When you rebuilt the head did you change the oil spray bay? Looks like lack of oil feed to that rocker TBO.

Gaszman, That sounds like a rocker worn to me. I'd whip the cam cover off and check the cam lobes from marking.

lol! ive just posted on your thread! yes it sounded exactly like that!
