Some heavy cleaning

Hi Its looks stunning !!!! really nice

Wow that's a lot of work! Very nice...

nice job!

just one little thing spotted on your car photo,
your wipers are too high, these should be almost under the bonnet
when on park mode.

hi quick question how did you clean that yellow stuff off tje intake manifolds? what did you use?

Grewal,

I scraped it off with some steal wool which you normally use to clean pots and pans. (Oven cleaner also works, but I find that dangerous stuff regarding all the hoses.) It's a lot of work but the result is nice. Another member used a steel brush, but that seemed a bit radical. Nevertheless, that also gives nice results. After cleaning it off I spray painted the manifolds.

also i would like to add that this yellow stuff provides anti rust protection,
so bear in mind to protect it somehow again to avoid rusty chwasty

Hence the spray painting.

hello thanks alot for your help guyz but i got one more question what sort of paint did you use becasue i know thers alota heat in the engine so is there some special paint ? and is it white or gray?

I used heat resistent paint, which is not very expensive. I think it was about 10 euro's a can and you can buy it at any DIY store. The only problem is that it doesn't harden at 90C but at 120C. So it takes a very long time to harden, because (hopefully) the engine doesn't get that hot.

Jimmya,

The stuff your mechanic may be talking about is a product called Zymol Strik.
This is a non-caustic, citric (oranges and lemons!) oil-based liquid used for removing Cosmoline and is also a good engine/general degreaser.
Zymol is (I think) a US-based company and generally provides high-end waxes/polishes/cleaners.

Their products are available in UK through vertar.com but are **** expensive ! (check out the prices of some of their waxes)
Zymol Strik is presently £34 for a 250ml bottle !!!
Can go a long way though, as can be diluted with water depending on thickness/hardness of Cosmoline.
Have used it on a new car of mine abroad that still had Cosmoline patches on exterior panels. Worked ok, diluted with water and sprayed on with eg small perfume or plant sprayer.

With remains of that bottle, I'm going to have a go at the valve covers and inlets on my CSi.
Don't know how good it will be at removing 12 year old baked-on Cosmoline ?!

Martin like you I am interested in removing 15 year old Cosmoline. Although I am off to the states so I may have a look for it there.

I used some paint stripper from B & Q.
I removed the intake manifolds first and all the attachments before using the paint stripper. This job is best paired with renewing the rubber fuel lines, rocker cover gaskets and intake manifold gaskets.
The results were amazing

How much time did it take to de the job? I'm asking this because I'm thinking about changing the rocker cover gaskets.

I would really like to see some RUSTY aluminium intake manifolds please!

Most paint strippers will remove the cosmoline but do not be tempted to shot/sand/glass/bead blast it off unless you completely seal off the manifold internals first.

The bare aluminium will need some sort of protection from OXIDISING once stripped, which means paint, powder coating or lots and lots of polishing.

With the manifolds off you could hone them and port match to the new gaskets.

IM job estimate is 10-12 hours plus cleaning time. Add a little extra for cam cover gaskets and banjo bolts.

You only need to protect them if you live where there's lots of snow or salt in the air, Here in most of the states it's no problem!
