Just pulled the head on my 484.
The inlet ports on two of the cylinders are caked in carbon/burnt oil from poorly seating valves (hopefully not worn guides).
I've already scraped out most of the carbon/oil from the ports. So, short of taking the head to be dipped, what are my options for finsihing off these ports and generally cleaning the whole of the head of oil ,etc. before grinding the valves back in and refitting to the block?

Thanks for the comments guys. Think I'll go down the scraper and wire brush route.....not that much to come off now anyway.

Hi, there is a product that mechanics use to clean the throttle bodies on a fuel injected car engines. I don't know the brand name all I know it comes in a spray can.

Did you get pistons and sleeves out yet?

Hi JB,
Yes I took the sleeves and pistons out the other night.
Not too much of a drama although it's not something you can do on your own. We actually used a soft aluminium drift and a sledgehammer used with care. The sleeves are only held at the top of the block by about an inch, so once you've got it moving it comes out really easily.

Turns out 2 of the 3 cylinders had broken rings, so I'm feeling very justified in carrying out this work!

I just need to clean up the head and sort out the valves. There's a question mark over a couple of the valve seats which are looking a bit pitted, so hopefully a good valve grind will do the trick. If not then I may need to get new inserts put in.

I'm putting together a web page that will cover this project, so I'll keep you posted.
