The mayo on the cap will be condensation mixing with the oil from the plastic cam covers on them.

Engine flush to my knowledge

if you're worried,just flush it with cheap mineral oil.

That's what I'd been told of before, mines already noisy from the timing chain! Maybe I might leave it as its running fine maybe just flush it with a few litres of clean oil instead!

Made my silent LET tappy as fuck. Garage did it without asking me first.

Think it's Lucas stuff, I've always avoided it but only due to hear say, think I'll try it can't see it doing any real harm other wise surely they wouldn't sell it, I no vauxhall offer it when you take your car in.

Never had any problems using engine flush's.

I stuck a bottle in when I serviced the Golf last week. Had no issues yet.

Used loads of forte stuff over the years with no problems

Heard about engine flushes thinning the oil out so it removes it easier, from the likes of bearings
But it can stay in there, resulting in thinner oil being present in bearings which rely on decent oil for lubrication.
Id stay away from it

i used this when i serviced it doesnt tap anymore and doesnt burn much oil any more

would highly recommend it

Im going to try it using b44k soon.

I wouldn't touch it myself

I was thinking of doing the same on my corsa to try reduce the tapping when its cold.

Would thicker oil work?

i been told that it can damage valve stem seals but i dnt no if its true

I've always been told not to use them and just do regular oil changes instead.

Going to be servicing my corsa c 1.4 twinport in a few days, question is ive got some engine flush as I've noticed some
Gunk on the oil cap, not loosing water so just condensation, oils pretty dirty so guessing its well over due a service, do these flushes works any bad sides to using them?
