e30 325i sounds like a diesel

[imye30]

have a listen on you tube can any one tell from the noise what this could be hope its not as bad as it sounds

[makman]

get a long metal object like a screwdriver and press one side to your ear..then go along the cylinder head with the otherside....like a doctors stethascope lol...youl hear an irregularity on the problem area..wether it be a snapped rocker arm or big end bearing etc. it doesnt sound like a misfire bit to eliminate it go through your plug leads by removing them and seeing if the noise changes.

[maxfield]

That ain't a misfire.

Pull the rocker cover off and have a look for something obvious like a snapped rocker. It's only a few 10mm nuts.

Although the problem sounds more bottom end and with the post you put about oil pressure light doesn't look promising.

[makman]

ah i didnt know you was having oil pressure problems also ^^^^^ what max said lol

if theres no rocker arm damage etc...drop your oil and check for metalic particles..if there present then its bottom end damage

[imye30]

I think it's oil pressure the oil light does come on an flicker wen driven

[maxfield]

Red oil light on the instrument cluster?

[jmc330i]

I would think that's bottom end

Had the same on my 1st touring, even the bit in the vid where it goes quite for a few seconds, then starts knocking again.

[imye30]

if its the bottom end is that a lot of work an what sort of cost can that be

[maxfield]

Be easier and cheaper to put a known good engine in.

[imye30]

nice one cheers to be honest it was up for sale been told might be a good idea to break it for parts as i need a small car now women hey

[e30topless]

low oil pressure = starved top end which leads to broken rockers, and that's what it sounds like it has

[makman]

has it been regularly serviced mate?

[imye30]

low oil pressure = starved top end which leads to broken rockers, and that's what it sounds like it has

Is that expensive to get fixed

[HairyScreech]

Nasty, either a broken rocker or a spun shell, either way lots of work to sort out.
