Well the rangie is finally working again. Have to say a big thanks to Dave for his assistance with all the work or should that be his work and my assistance. For those on the Pacific Pines trip in late August may remember that I was loosing a fair bit of water, originally we thought it was the welsch plugs, partially it was, but the main culprit was the head gasket which from memory was leaking in about 2 places. This was also over pressurising the collant system causing the welsch plugs to leak. This was the reason I then missed the Coffs Harbour trip and everything since. I was kinda
as the car was all packed ready to go and I was lucky to make it home from the mechanics. Unfortunately we did not realise how stuffed the motor really was.
Oh did I mention that I had just had the gearbox removed to replace the welsch plugs at the back of the motor which were leaking (this was the Wednesday, leaving for Coffs on the Friday)
Step 1 - heads removed, in for quote, fully rebuilt and the injectors etc all serviced at the same time. 9 valves didn't seat properly and the heads were warped. Then was suggested that would need to re-ring due to the heads being new
Step 1a - Mechanic said that the heads had previously been machined and done incorrectly, so in hindsight my/our theory is, engine had been seriously cooked prior to my ownership (maybe why it fairly cheap at the time) The radiator was quite blocked when we purchased it. So would suggest that it was only a matter of time until the heads let go due to the fact that the block had no hardness remaining.
Step 2 - helicoil threads in block - couldn't be done as not enough space to get accuracy, (which in the long run has probably saved us) so block removed from car, engine fully stripped, bores & pistons looked ok within tolerance anyway (we were originally aiming for the cheap rebuild - it didn't turn out this way), bearings well some were average, some ok and the one was completely grooved - photos exist of it somewhere. I cleaned it all as much as I could.
Step 3 - what about having the EFI fitted to the P76 (P76 motor has a holley on it which didn't work for me off road). Found that the inlet manifold spacers are available as are the ZF adaptors. But no shops that I spoke to were interested in fitting it. Would then have all the garbage with trying to relocate the airconditioning and rewire where necessary and find a computer to drive it should the standard one not be sufficient. So decided to stick with the 3.9 as the heads and injectors had already been completed.
Step 4 - take it too engine builder/tuner - this is about when it really when completely pear shaped.
*5 liners had movement
*pistons warped
*lifters stuffed
*cam stuffed
*block had lost its hardness - had to be re-heat treated twice to get it back to correct hardness
*crank scored/marked
Step 5 - all of the above repaired/replaced/rebuilt
Some might suggest that it would have been cheaper to buy another car, in the short term quite possibly, but I have already done the quite a bit too it that would more than likely have to redo it all with a different car that was within my budget.
Install 1 - finish off rebuild of engine (valley cover and inlet manifold/injection) and fit motor into car attach to ZF
Install 2 - dummy fit starter, extractors, air con, power steering pump etc (for those that might forget, put the extractors in prior to the air cond and starter
Install 3 - properly fit all the above, hook up all the electrics, correct the orientation of a spacer/gear - which meant removing some of the above and added several hours into the process. Was not impressed as we discovered this at 11.30 Friday night.
The motor started first go at about 5.00am Saturday morning, sounded a bit rough as we put 3 of the exhaust gaskets back to front - easily fixed in the afternoon after some sleep.
Now to run it in so I can then come on trips again. Will let you know what the power/torque increases are like after it settles down. Its still 3.9 and the heads are standard but thats all
Next on the list is the heater core as the lower pipe decided to seperate itself, oh and quite possibly some axles in the near future.
Happy Xmas everyone
Guy

yep but that was less than the projected cost of the do it with a cheap rework of the heads to make them flat and new gaskets...
this was one of those jobs that didnt show all the faults in one go.
when measured the block face was flat but the heads were warped. so head work was the order of the day.....
then a couple of bolts didnt "feel" right so the decision to helicoil the block was made.
after that it was just one long daisy chain and a case of sending good money after the bad....
IF Id known that the block didnt reharden correctly on the first shot Id have scrapped it then and there but unfortunately I wasnt there and didnt find out about it untill it was already done..
but with all of that its got a new cam and some hi comp pistons so theres some silver lining in the clouds....
I was amazed when it started first go... after doing an all nighter to sort out the dizzy drive gear and finish the engine install I was sure I was going to naff something electrical.....
Ive seen shattered looks on bloke before but the look on guys face when I did the oh crap it wont run like this thing when i couldnt get the dizzy to engage the drive gear..... after everything else that had gone wrong for him on this one if it wasnt parked under his house I reckon there would have been a rangie flambe on the menu.
oh well ass beats class I guess..

Subscriberwell good work dave and guy, you now have a 'known' good engine.
sure lots of things go down wrong as you get into a job, and i know only too well how it happens, rovercare, go easy on guy, he's had a bit on and dave's been hard at it, hindsight is 20/20.
hope to see you on a track soon guy, we will get into the new call sign to, more suitably too.

Hehe, normal for the dirty old rover motor, frustrating *****s they can be
RoverLord
not helped by some nufti posing as a professional engine builder getting the spacer and drive gear nipples about so it was no where near the dizzy,,,
Never thought to look at it before we put it all together and as close to the last thing I was going to do was the dizzy and leads so they were out of harms way while we were putting it together and as I was sliding it in and rotating the rotor arm to get it to engage it dropped in place first go to which I thought "well that was a jag normally they're a bugger to get to engage and pick up the oil pump drive, I'll just give it a wiggle to make sure its happily in place and the shaft is ok"....
a look of befuddlement crossed my face as i turned it 360 degress.so I pulled it out to have a look see, befuddlement turned to utter disbelief which very shortly had guy looking less than happy....
Fun way to spend a night.. fixing other peoples messes.

Yep gotta love proffessionalsI have paid less than half a dozen people in my life, only 2 have done well, one is the bloke I get to do engine machining, blocks cranks etc, for obvious reasons, as in dont have THAT many goodies in the shed
2 was the local auto dude I got to do the 4L60E in my jag after I fried it in lees than 1000kms
horror stories like having my block in for the required machining after blueprinting still sitting on the machine bed when I turn up after 3 EXTRA weeks waiting, hence the new machinist
Valve seat dropping out on start up
Mild steel crown wheel bolts, hence learning diff's when I was 18
Not bad odds hey
EDIT the only other 2 I've paid for are exhausts, cause its a crunt of a job, just gone to a new guy after the last melted the paint on the back of my jag....and scored a job whilst there, wire a lexus 4l V8 in a jag
And about to try a different tuner, not real happy with this one
