Dipstick not staying in

[television]

i'm guessing its a very big (and expensive) engine to bits sort of job to fix piston rings

This is a hard question, if it is broken ring it is possible for oil to be pushed up the dipstick say at a constant 70-90 mph.


The best thing that you can do is to do a compression test, so simple, take out the sparking plugs and check the compression on each bore, they only cost £5-£10, if one is only slightly down you can leave it, it could go for years without changing much

It depends if the engine has to come out and if there is any bore damage. It is possible to remove the sump and head, take out the big ends and push the piston up though the top. Bad news is that if the engine has to be re machined then its probably more cost effective to fit a replacement engine.

Were you around Ian when we re bored in situ.

I'm beginning to feel like rufman here, i've lavished this car since i've had it where normally i would bin the car off and get another, but things seem to keep rearing their head and need me to spend more money, money i am extremely short of now.

I remember it well. Had a V4 Capri done in situ. I was only relating what could possible be done on your drive. Not yours in particular But A drive. Not knowing what the gentleman in question has, or is capable of (no put down intended).

If the car drives ok why not just leave it if it drives OK

Come on you old timers retell the tail of reboring in situ. Surely all that swarf must have been a nightmare to remove. from inside the block or had they some super sucker to remove it all?,

 

[blue190]

the car is driving ok but i don't want it to fail on me when i'm in lane 3 of a motorway. and i don't have a drive or the space to be taking my engine apart, so it would be a garage job which means ££££

That was not a problem Nigel, it fell straight through, you had to remove the sump to take the pistons out.

The worst aspect was that we used air lines in those days to blow it all out, sadly it often pushed it tight into the corners and other places, but you could not see it so it did not matter, dont forget that the life of a ford Anglia / prefect was just over 25k miles before the ends went

Please do not worry it will not stop as long as you have good oil pressure, and this fault is nothing to do with that.

Under the worst possible case it would only fire on 5 cylinders.

Please relax it will not stop through this fault,if it is a fault

swarf ? rebored , not redrilled .

An engine that has been cooked can break a ring or two , and you mentioned that a head gasket had been done - don't kid yourself though , if you have broken rings , they can break up further and make a right mess of a pot and piston - oil pressure or not - get back to basics , find out the cause of the crank case pressure , blocked breather or whatever , if you can borrow one , a borescope can allow you to have a look at the condition of the bore to see if the ring has done any damage - but whatever you do , deal with the problem before you have to .

Each to what they have found in the past, I have known cars to run for years with a broken ring.

An easy test is the compression test, if one bore is down, and oil is injected to that bore and the compression come up, then it is just wear and not a broken ring. It would appear that the engine is not missing to any degree.

Of Course Malcolm , of course - however actually determining a broken ring isn't that easy , until they wreck the bore .

Indeed its a hard world out there Fred, my only thoughts are here, would he go for a rebuild or secondhand engine.

I do agree completely that a bore scope would be a good idea

i do admire you're optimism television, in that my engine will happily carry on on 5 cylinders when it only has 4 to start with.

LOL..

Before we all get carried away with blown rings let's just get back to basics. check the breather system for any restriction or blockage.
If rings are broken the engine normally breathes really heavily from the breather and dipstick tube.

Unplug the breather from the air filter and see how hard it's puffing, if just lightly then it's Ok, if really heavy then possible broken ring, if nothing then it's blocked.

A cylinder leakdown test is the best way to find compression loss.

That an easy slip to make and it does not alter anything

 

[MBManInKen]

There we go again!

Dipsticks not staying in; heavy breathing;...
I am appalled!

wasn't having a dig, and all your advice is much appreciated, i was just wondering where i was going to gain 50% extra on the cylinder front, although they would be handy as redundant back up i suppose.
