Cleaning Cylinder Head

[Guest art b]

ive got a grubby cyl head that i want to work on,[portin and new cam]

 

was gonna soak it in gunk and petrol, then take it to a jet wash and blast it clean, then pop it in the dish washer for a wash,

 

any one see any problems wiff this plan??

Depends whether you've got a wife or partner

Jeez, what ya gonna do, eat off it??

 

Let it soak in parrafin then brush off all the grime and rinse in clean paraffin. It is as cheap as chips and dries quickly to a non-greasy paintable finish.

[Guest docter fox]

does it have to be that clean?

 

I'd be interested in your approach to the porting, as it's something I should be doing soon

well took ya advice and gunked it poped it in a plastic window box £1.99,

and brushed it over wiff petrol,

than filled the window box with some other grubby bits,and topped it up with paraffin,

willl leave it to soak for a few days then start cleaning it up with a wire brush on a drill, followed by porting with my trusty dremmel!!!

mix up a mild alkaline solution and let the head sit in it for 15mins, for how ever long it takes to go all brown/black foam .. removes all the carbon from the exhaust ports and all the grease from everywhere..

 

I use NaOH, sodium hydroxide or draincleaner, works a treat. Make sure that you rinse it off with some weak acid solution like 50/50 vinegar in hot water to neutralise the pH..

Hi

 

In my previous job we used a soda based hot wash for degreasing

large bearings and general gunge removal.

 

Have done this at home with ordinary household washing soda

and water and then boiled over a gas jet with excellant results.

I hasten to add not on the wifes cooker ,well not when she is in.
