URGENT oil pressure stop engine
Pesky jones:
Ok well thats good.
When turning clockwise on the first rotation I did hear maybe two clicks that were slightly louder. So does bent valves or valve guides mean new head and not new engine? Could the rods be bent?
doylebros:
Anything is possible but let's just relax and give your mind a rest - Saturday will be there quicker than you think and you'll have a chance to see the outcome unfold before your eyes.
Do your sums on an exchange engine from a breakers yard and you'll have your ball park figure.
r5gtt:
I personally didn't want him to do it just in case there was metal to metal friction but now I've see the video all sounds promising from here on.
As doylebros said, that's the compression stroke.
If the rods were bent you'd get no turning of the engine at all :happy2:
If valves are bent then all you'll need are cylinder head gasket, valves, guides and seals. Maybe a timing kit and water pump would be good at this point of you've not done so already. sorry so many posts I forget who's done what to their cars :stupid:
Happy to see its not the bottom end goosed :smiley: :smiley:
Chris92:
I don't see how turning the crank shaft by hand could possible do any damage without the sump on, oil pump won't even be working at that speed.
Valves won't be bent if there's compression
Engines can still turn over with bent conrods.
r5gtt:
I would think having no oil to lube the metallic components would score certain parts but maybe I'm thinking about it all wrong here? .
If the rods were quite bad then I'd say it wouldn't as I recall ad having bent rods in an engine I bought second hand in my youth not realising the fecker conned me out of £60 at the time lol not big money but still hard earned money. Not evidence of engine knock was mentioned by Pesky so lets wat for his dad's mates opinion on this.
