sounds like lifter tick to me, has it been run a lot in the last 12 months ? my old bmw used to have lifter tick with so many short runs.
Not really, been the kind of car it is, I am also a little afraid to now take it anywhere just in case it is something serious, plus the PS leak I fixed is now back big time, seems the pump itself is now leaking big time, guess it found next weakest link, as such I have a new pump/reservoir on the way which after that will only leave the module as only unchanged item in the PS system so any luck will be on top of that.
Back to the engine got lots to look at, getting a lot of mixed messages from US side.
Some say at idle oil should be squirting everywhere from rocker arms and some argue that mine is absolutely fine, so its a case of do I have an oil flow issue or is that normal. Oil pressure is good, but good oil pressure does not equal good flow necessarily.
Many are also saying worn lifter and or camshaft and check #6 cam lobe first as it gets most wear.
Also a few have said they had same issue and it was not engine but things like crank pulley bolts backing out and catching and a new favourite is the TH350 transmission could have a cracked or broken flex plate, so I am gonna remove transmission cover and check that out with it running.
Also been told to listen to fuel pump as supposedly they can make a similar tapping noise too and are generally noisy.
Another one is to check exhaust manifold gasket on that side also, could be reason, so there is a lot to look and listen to before doing more engine work.
Its in a local garage Monday, who have a good reputation and understand classics somewhat, so gonna see what they thinnk and let them know all feedback I've had from US side. Also a guy I know in Stoke put me in touch with his mate who owns a garage and has good understanding of classic and Chevy small and big blocks, so he is my next stop.
Its really difficult as many say its fine, drive it, otherwise have no clue but don't want to look at it and then finding someone you actually trust who actually knows what they are doing is not easy.
I could do the lash, pull the lifters and it could still be present, hence gonna let some mechanics with better hopefulyl better understanding take a look before I start pulling it to bits, though I can now get the valve covers off in about 5 mins per side and intake manifold seems an easy affair to remove....
Unfortunately for me my hearing is very tuned into car noises, I hear a squeak, knock I have to fix it, most people who have seen the Corvette are just wowed by it and can't even hear the engine knock, I think there is absolutely a problem and maybe with more use it could go away, but it could also get worse and result in a major engine rebuild or replacement which would be a shame on a matching numbers car to drop a crate motor in it.
