nearly done

that's all the good news, now for the bad. after changing the fuel pump and replacing the dodgy ht leads. i ran the engine for a couple of hrs today. the bad news its breathing heavy from the rocker filler caps and even worst it smokes. really heavy when you rev the engine. I'm gutted it runs sweat great oil pressure, just frigging smokes.

So where do i go from here. engine out and de glaze and rings, for now as much as i would really like that 383 >> 496 stroker kit from 440 source. i think it will have to wait. hmmmmm does the engine come out tomorrow or shall i get leathered tonight.GRRRRRRRRR!!!

Get leathered! After looking at your amazing work you deserve it!

sorry to here motor smoking / blow by !! just a thought looking at your picture , what have you got on the rocker covers looks a sealed cap on one side ?? what about the other ?? PCV to carb on there ?? or

should have an open breather or one piped to air cleaner on one side & & PVC on the other

or open breathers on both sides

high stevo i have a pcv valve on the other side changed the cap to a vented push in today. wondering if its worth runner the engine down the road to see if reduces the smoke before i pull the engine,

hey nik make sure your breather situation is correct then run the mtr a while get some miles on it, maybe it has a stuck ring that may free off etc. dont pussy with it get some revs on it to try n bed the rings in etc, whats the worst that can happen,,,,,,,,,,,,,,,,

thanks dunc was thinking of trying reddex.i take it mopars breather heavy then.i've got till the end of july so worth trying to bed them in before i pull the motor will do a compression test as well.

two things that were already done when i bought this car was the engine that defiantly is smoking ran it again today half a bottle of reddex on a local business park loads of reving it still smokes. on light driving its fine, just when u boot it.looks like the engine will be coming back out. the second part i left to chance was the rear axle guess what on left had bend only it grates like a milkfloat. 8 3/4 lsd. come on tell me the worst.

thanks kiwi will check the bearing end float and see if the drums is rubbing the back plate tomorrow.

Sorry to hear this Nick. Is the smoke out of both exhausts?

Check that the PCV valve isn't stuck (should rattle when you shake it).

It could be the valve stem seals, especially if it smokes when you get back on the gas after deceleration (e.g down a hill). Still means heads off to replace them (or the old rope trick), but easier than engine out.

gearbox has been cleaned up with new filter

Any more details that that?

Did you do it yourself or at least inspect the work done? (Edit - sorry just read you didn't)

If it is smoking out of both exhausts it is (as already said) probably rings or valve guides. Or too much oil.

Make sure your dip stick is not too short (seen that before) and run the engine with the oil at the MIN mark to see if that helps any.

You have LSD oil in there and not regular gear oil yes?

Could be sucking oil past the valley pan into the inlet ports. Did you use any intake gaskets?

no seals on the inlet valves?

or mashed em on start up?
