ALFA GT 3.2

Wave gt 3.2 engine cleaning advice

Hi My Gt has done 40,000 miles and want to clean the engine . Im really talking about the heads and chrome tubes. The tubes have started to rust and the heads look tired. The engine has never been jet washed and wont do that. I want to know what is best to clean the heads. What cleaner gives best reults and the best cleaner for the tubes. The rust on the tubes is at low level and appears to surface. I have seen pictures of alfas with shiney heads etc and would like to achieve the same. any advice please post reply

Re: gt 3.2 engine cleaning advice

Don't know if a product called "Brasso" is available in the UK? Used it in South Africa on the tubes, it works very well.
Alternatively there are some very good metal polishes that you can get for alloy wheel rims, especially the deep dished type, Maguire's have a product for rims that works well on the tubes.
Alternatively if this doesn't do the job, the best way is to loosen the plenum, remove the tubes & send them in for a repair.Don't think you will need to do that though with surface rust.
Hope this helps.
Ciao,
Monstro

Re: gt 3.2 engine cleaning advice

I have been thinking the same for a little while. I had an oil leak from the rear main seal that threw a little bit of oil around the engine bay. I was thinking of using a small amount of degreeser and wiping away what I can.

You're right to steer clear of pressurised water. That'f fine for pre efi engines, but spells disater for modern electricals.

I was wonbering if one of those steam cleaning machines may work if you avoid the electricals (you would need to be careful).

Re: gt 3.2 engine cleaning advice

so long as you adequately protect the electrics from water, it is no big issue to 'wash' the engine bay, but i'd only use low-pressure water (garden hose) rather than high-pressure. it is common practice for pro-detailers to wash engine bays (incl modern cars), so i presume it's ok (NB: i've not done it).

i usually refer to www.detailingworld.co.uk for tips on detailing.

Re: gt 3.2 engine cleaning advice

I am not sure to use metal polish on the intake chrome pipe. It looks like it has got a layer of treatment and you don't want to polish it off. It's like the chrome grill we have on 156. You will eventually polish the chrome off if you use abravsive polish like Brasso or Autosol. They are good for Exhuast tip but. I could be wrong if it doesn't. I use 3M Stainless Steel appliance spray cleaner. It works well and is not abravsive.

Re: gt 3.2 engine cleaning advice

I think the intake pipes may be made of stainless steel and not chromed? Anyone else know for sure?

If it is SS then you can just use any appropriate SS polish/cleaner

Re: gt 3.2 engine cleaning advice

Well I have used autosol on the intake pipes with no issue.

What do people use to clean the rest? No way I am spraying water under the bonnet!

Re: gt 3.2 engine cleaning advice

sometimes it only takes a small 'mark' to 'damage' the chrome to result in rust. so i suspect the chroming is not a thick or top quality layer.

perhaps that's the situation here. 'mild steel' pipes with dodgy chrome plating.

Re: gt 3.2 engine cleaning advice

That's why I am hesitate to use any abrasive polish like Autosol on the pipe. I don't wanna find out it is not stainless steel in a hard way.
