My Second M50 Engine......

[Baz666]

I`v now had my car on the road for a month now and its been superb to drive, but last week drove it home parked it up and for some reason when i went to start it on the evening to go to work it started to tap (yes like one of the tappets have gone on it) can any one tell me what sort of job this is to do on an m50 or would it be best to dump it and start again.

if anyone know the cost of this job as well can you let me know.

What condition is the exhaust manifold in, would it be that baz?

[DanThe]

Have you checked the oil level?

[Baz666]

Thats the second time someone has said that will
Have to get it looked at...would the tapping from the manifold
increase with the revs.

Should of stayed with the m20

[Baz666]

Have you checked the oil level?

Yeah all good Dan.

[Baz666]

on the m50 are the tappets adjustable or are they hydraulic.

[E30BeemerLad]

hydraulic mate

[Baz666]

is that bad news then if there hydraulic.

[E30BeemerLad]

check a load of daft things Barry like are the spark plugs in tight, is the exhaust manifold tight to the head, is the lambda sensor in tight?

Where does it sound like the tapping is coming from, top of the engine, front etc etc

[Baz666]

well its hard really to hear where its coming from so heres a little video so just incase you might know from sound in the differents, also is`nt the sound of the engine suspose to dye when you take of the oil cap off and spit out oil.

[E30BeemerLad]

I can't watch that at work mate, so will have to look at it tonight (but I'm no expert on this crap anyway)

[Speedtouch]

That's a clunker alright

[Baz666]

ok Thanks

That's a clunker alright

thanks for the obvious

[baptie0]

I dont think it sounds too bad, possibly a sticking hydraulic tappet. you could try some engine flush, get the engine nice and hot and change the oil and filter. then thrash it, the m50s are bomb proof

[Baz666]

like the sound of that fella

[DanThe]

Thats defo a sticky lifter, sounds like your vanos is having a groan also

[E30BeemerLad]

Do you know what grade of oil is in it Baz?

[Baz666]

Yeah Dan it is a little but when the bonnets down you dont hear it.
Whats the best way around a sticky lifter.

[Baz666]

Do you know what grade of oil is in it Baz?

I think it was something like 5/40 grade if this is wrong let me know what to go for.

[Baz666]

Use a diesel oil for a while

really what stuff do you reccomend

air leak cheaked all the pipes didnt think i had one.

[Baz666]

5W40, 10W40 (as close as you can get to these) Not sure what grades are available in the UK? (Diesel oil has strong detergents built in to help keep the engine clean)

You must have a leak somewhere, removing the cap should result in a noticeable change in rpm.

Thanks will i`ll look into the air leak, i just carnt get my head around using diesel oil but if it works i`ll try it,

sorry to ask this but can anyone else back up what Willnz is saying.

[E30BeemerLad]

Yes, Diesel oil is safe to use for a bit.

[Baz666]

thanks buddy but how long is a bit as i would hate to do damage.

[E30BeemerLad]

I'd probably do about 200 miles and I wouldn't rev the fanny off it, but it's probably perfectly safe.


If you're brave, parafin & gear oil & leave to tick over for 20 mins would clean her out

[Baz666]

ok thanks going to try and sort it this weekend....engine flush and diesel oil

[E30BeemerLad]

just diesel oil Baz, no need to buy engine flush too

Have a look here mate

[Baz666]

Thanks for that buddy, great read

He talks about doing it to a vvti and as i dont know how much oil one of them takes
Would i do the same 3ltr mix.

We have diesel trucks at work so i can get my hands on loads of them both.

tonight at work i`v got myself 10ltr of 10/40 diesel oil which we use in our trucks from volvo and about the same in transmisson oil which is the same thing isn`t, will these both be ok to use let me know as i`m going to give it a try sometime today.

what i need to know is how much to use...???? the same as if i was butting fresh oil in.

he is adding diesel to the oil, not using diesel oil.

[Baz666]

Its 4 litres of diesel oil and a litre of gear oil.

[Baz666]

Right this is my first mix its as above 4ltr diesel oil and 1 ltr gear oil, i will show it as they have done on the website that beemerlad put up....hope this is going to work.



this is not a cherry drink

once it has done it first run i`ll put up pictures of the results.

[E30BeemerLad]
