For those that might have followed the GNU saga when it was Tunnies project, and which is still ongoing in my care ..... I have finally solved the elusive tapping .... old engine out -- new one half in.
The noise? ...... piston slap! With the old lump stripped down you can move the pistons side to side a fair bit.
Anyway --- lower mileage lump going in, along with the newer gearbox. New back box too.
Fingers and toes crossed ;)

I must admit, it sounded much more lifter related.
Although I agree with your course of action, that old engine was badly abused, so a new, known good lump will be a better option :y

It wasn't piston slap....it was no oil to the cam area.....couldn't belease how dry the top end was!
Remember that the V6 has slipper pistons so you do get some movement.
Also consider that the piston crown expands a lot so is quite a sloppy fit when cold
Plus, pistons generally dont wear at the top end, its normally the bores that show the signs in the form of a worn lip.
-
Top end, once lubed up, looks in good order.
Oil wasn't getting lifted to the top because the bottom of the sump had been dished in and blocked it off.
The old lump does look like she was badly treated in her early days, before being rescued by OOF.

It was not rescued by OOF!
The lump you removed has cams and lifters in it that were rusted! (it must have been exposed to the elements for bloody ages!)
I seem to recall donating a load of known good lifters but, that only works if the lifters are getting oil (they wern't!)
On the pistons, if you ever look at one closely when removed they are actually smaller at the crown than the skirt. The reason is that the temperature is hottest at the top and coolest at the skirt (oil cooled) so they expand differing amounts and hence the shape they are mad to.
The noise was definately top end!

Sorry -- in my clumsy way I was trying to emphasise that the engine had been given a rough trot before it came into the ownership/ care of the OOF members I know had worked on it

Lol, sorry, I had a falling out with the original person who worked on it due to his corner cutting and bloody mindedness through not listening and heeding the advice when working on this one.

If you know any one who needs a boat anchor then the old engine will make a good one :D

Well -- she has had a bit spent on her, with the new mechanicals, bit of a spruce ( new grille) front and rear bumpers resprayed, rear shocks matched up ( one was self-levelling, t'other was not!) all the better bits from the donor swapped over, new battery, soon to get rear tints, and eventually some firmware updates --- hopefully she will be a new beast!

It was over the:
Fitting an unknown cheap nasty early engine
Non-gen cam cover seals
Not bothering with the manifold gaskets
Badly fitting the gearbox so as to destroy (as was found out later) the torque converter because the advice of fitting it to the box first was not heeded.
Then posting that there crap which was totally due to an incompitent worker who didn't practice what he preached!
The bodges I witnessed on some of the cars he bought was shocking and I could take no more!
-
Lol I cannot argue - I've learnt a lot from you :y
I fitted my first autobox the "wrong" way by leaving the TC in place - found it more hassle than fitting it while located on the dogs, though!

Hopefuly, Marks DTM, this one can be resurrected -- be a bl**dy expensive (and large) paper weight if not :o
-
It sounds like you are taking the right approach and not trying to do a quick bodge :y

Hope so -- bottom line is I want a car that will run right and long! And bearing in mind that it will be carrying my wife and family it will not be bodged.
As, it seems, others have discovered, a bodge job is a shortcut to nowhere (or oblivion if very unlucky!)
-

Thats one thing its not is a bodge. The new engine before it goes in has had (all gen part) new head gaskets and bolts, new stat, new oil cooler plus gearbox and TC that has done very little miles so with a bit of luck on Monday she should be about ready to come out on the road :)

Excellent, do it right and do it once :y

In the service book there is a stamp from an auto gas company in london who i take it fitted the gas system. Well if it was them lets just say they should be shot.

I should add that the old mixer system is out (should never have gone in a V6) and a front end upgrade to sequential on the way in

I remember this car - and I remember the person doing it! :-?
-
The engine in that car wasn't the original hence the whole front end of the gas system had to be replumbed and wired when the engine was swapped. Just a pity the standard wasn't very good but then it matches the rest of the sad engine swap (well two engine swaps actually) story.......

Well when there is a meet down this way you should come and have a look as its much better now :)

Seems like a lot of people know far more about it than me -- I think HN03 and I have discovered all of it's gremlins ------- unless anybody knows different :-?
(When I say "HN03 and I discovered all" ... HE discovered -- I watched helplessly ::) )

Get to Newent - I will be visiting for an afternoon

Can I ask ( dare I ask) who was the previous owner ??

Can I ask ( dare I ask) who was the previous owner ??
2 members here, me, and someone previous who has left.
I sold it to a guy who picked it up on a trailer... like to add when i sold the car, it went with Elite alloys, not CDX which it has now.
I lacked experiance to fix it right, it did need a new engine.
Unfortunetly i picked it up from the guy who MarkDTM had a fall out with...
I was not impressed with his work, incorrectly fitted torque converter, feked the gearbox. Exhaust manifold nuts..... there were 3 differnt sizes!
I lacked experiance, and eventually time...

Whispering........ I wanted to know that too, just in case I have got the wrong idea you uderstand. ;) ;)

Tunnie -- the guy who picked it up from you is my son in law. Wheels have been changed a couple of times since ( can't decide which I prefer!!).
I bought it fully aware it was a project car in need of major work -- it was in no way mis-represented and I have no complaints there.
All the dodgy stuff has been replaced with GM and, fingers crossed, she should be running unaided next week!
I would like to make it clear to anyone reading all this that there is no fault with Mark, James or Tunnie here and I am grateful for their help and advice in getting poor old GNU back where she belongs.

All I did was run some coolant hose, and plug a connector in ;D
Good to see her in good health, though :y
What about the speedo / TC problem?/

Hmmm -- in the albeit short runs I have had in her, haven't noticed TC or Speedo probs.
Mind you, she hasn't been well enough to put TC to the test!

Hands up - when I first started tinkering with these cars I thought that all the comments for needing genuine gaskets were a bit OTT and tried pattern ones. Needless to say, I soon learned from the error of my ways after doing a few jobs twice ;D
Having said that, when we did the HG on my current 2.0 all we had at the time was the pattern camcover gasket, so I used it with the intention of getting the GM one fitted ASAP afterwards.
At first I thought the pattern gasket was leaking a bit externally, but I'm not so sure, no oil loss and none in plug wells - and it's done 4k now incl the lakes trip and one to Wigan on a pattern part.
I must say, I suspect it's a time-bomb, waiting to blow ;D
Genuine GM all the way...
-
As MarksDTM said -- better to do the job properly, ONCE !
TBH, for the sake of a couple of quid, it's better to go for the real deal. And. once she is up and running properly, I don't want anything needing to be stripped down again for some time.
