is an engine flush a good idea?

[rydogg09]

we all know the vw,audi, seat engines can become quite dirty engine quite quick, so was wondering if a engine flush was a good idea to get it cleaner? thanks

you'll find opinions divided on this, some say yes others no.
i'm in the NO camp just do a couple of oil changes close together that should clean out any rubbish.
the thing with flushes is that you'll never be able to get 100% of it out, and as they are designed to break down oil , there will always be a little bit in the engine breaking down the brand new oil.
and you might have carbon build ups plugging gaskets and all sorts so once that's taken away it may start rattling and leaking oil.
I'm only speaking from personal experience of flushing an Cav SRi 130 out and after it rattled like a bitch for about 3 months untill the oil filled all the gaps back in

NO is my answer too.

No don't use flush mate when i had a pulsar I lost oil pressure after flushing if ya search net you'll find opinions

 

[Richy Cupra]

I used it when I did my oil change last year and iv had no problems at all. People do have mixed opinions with additives, such as injector cleaner and oil treatment but iv never had any trouble with em tbh

Awesome did mine last year, no problems at all.

 

[allh2k]

I use it every now n then don't notice any difference

 

[rydogg09]

Usefull info still in to minds might just do 2 close oil changes. Cheers

 

[Gav_Kara]

That's ya best bet mate..

 

[alien1974]

yeah its best to just do regular oil changes as you are less likely to cause problems

One for the "yes" camp here. I had mine flushed last year when the turbo was changed. They did a flush then drained, new filter and oil and I was told to "take it easy for a couple of thousand miles and come back", they then changed the oil and filter again. Running lovely now.

I would say if you want to flush it then change the oil again after one or two thousand miles, that'll get all/most of the last residual bits of flush out.

Slightly off topic but on the same track... what about engine additives? injector cleaner, diesel treatment, smoke treaters etc?

 

[offitmassive]

NO!!!!!! do not do an engine flush on a turbo'd engine!!!

Well mine's still going strong so can't be that bad for it.

..+1

+1 for NO, the residue from the flush will alter the composition of the new oil, plus would be worried about the turbo bearings and your oilways getting clogged up by any crap that the flush loosens, I'd def go the 2 oil change route myself.

If the oil is changed again soon after the one immediately following the flush then there will be only trace amounts of the flush left, so long as it's done right.

And again so long as it's done right, there shouldn't be any crud left, that's what the flush is for.

 

[mty12345]

yh that's a fair point about the residue, it is only gonna be a very small amount left,. But yeah sorry, i should have made it clearer what i meant on the second point, i was meaning that some of the crud on it's way to the oil filter/sump has got to pass through oilways etc to get there

 

[8bit]

Well the engine flush is meant to break down the crud so as long as it's done properly and using decent fluids then the crud should all be gone

i did an engine flush and had no issues at all, car ran lovely afterwards
