Has anyone got an opinion on using an engine flush during an oil change? I am taking delivery of a Simca tomorrow that has been stored for 10-years. I intend on changing the oil and was considering flushing the block out first but have read on some websites they can strip surfaces and do more harm than good?

Check the condition of the oil that's in it first. Most old engines don't need it a couple of quickfire oil changes usually cleans them up. We use them fairly regularly on modern diesels that turn the oil into tar if it's not changed regularly and they work OK, but make sure it needs it first. If you drop the old oil and it comes out looking like oil it won't need it.

Some cheap ATF in the oil, say 1 litre in a typical 4-4.5 litre capacity sump, and run for 100 miles makes a great flush. And at least it's still a lubricant.
I first heard of it on ClubGTI, it sorted out rattling hydro tappets for me on my old Golf engine.

Whether you believe you can, or you cannot, you're probably right.
