Is there any easier way to remove old stuck gaskets ?

(1/2) > >>

McCabe-Thiele (Ted):
The block gasket on my 500 is well & truly bonded  to the engine casing - is there an easy way other than a scraper with the risk of digging into the soft alluminium?

Soak block in Paraffin for a couple of days?
Steam stripper?
Paint stripping heat gun?
Driveway Jet wash gun?

I don't have a Nurse Julie who I can deligate it to.

Nurse Julie:
Haha, my favourite job. Scrape the surface of the old gasket, soak with petrol, leave to soak in and scrape off what lifts. Repeat until done. Most of that gasket will come off it quite big chunks Ted by the looks of it.

Bryanj:
If thats the spare casing, looks alot better than when i sent it you Ted, you are getting on quickly

This is the bottom case after it's first two cleans with petrol including bottle brushes through anywhere they will fit - my third stage is the outside paint strip - my fourth clean is another petrol wash then finally I wash out the oil ways with more petrol then after painting (outside cleaned with thinners) I pump oil through the galleries etc.

I found some long bottle brushes (with handles) that I could trim to go down the main gallery under the crank Ted, the amount of crap that came out was unreal.
