How many members on here have suffered the slipped liner/cracked block issue with their P38?

I ask as another year ends and I tot up the cost of the P38 this year (not an anorak I keep records for my business;))

The cost on petrol this year has just topped £3,100 or £258 a month or £59 a week. Some might say that's not too bad for a thirsty V8 but the figures can be deceiving because the P38 has only covered 6,700 miles :eek:

I would LPG it tomorrow but at 101,000 miles the slipped liner/cracked block problem makes me think I might not get to see the long term benefits of the conversion.

The price of L322's seems to be on the slide and are becoming more tempting but there seem to be more and more posts with issues to the Mk3 these days and to say the least the prices on some of the spares are jaw dropping.

A diesel P38 is out of the question. Decent ones are too pricey, the lack of low down grunt means in our every day driving conditions and the higher price of diesel they are no more economical than the V8.

So if those of you who have suffered from a terminal engine failure would be good enough to reply and perhaps tell us your mileage at the time I would be most grateful and as always if anybody wants to put in their 2bobs worth I'm all ears or should that be eyes.
 
120k, not a complete failure, but I keep an eye on the coolant. Some people may miss the fact the cracked block thing can be very slight like mine, or severe, boil overs. then cause terminal damage.

Just got the block religned by a nice chap mark at hallbeck, engineering. I haven't had the time to rebuild because of a family bereavment. But total cost so far is about 1.2k for parts, doing the rebuild myself, slowly. Looking forward to getting the old girl back running.

She has been on lpg since 2008, bigas. Valves are in great condition.

Over three years on LPG so you've had the pay back so the failure although still a PITA, is somewhat softened. If ours goes bang inside a year the ear bashing from 'er indoors' (Who's decided she wants a Mk3!!) will be heard in Liverpool.

I'm OCD on the coolant. Flush it through once a year, any hose not looking 100% is changed as well as checking the level every time it leaves the drive!! Oil and filter changed twice a year. But luck of the draw seems to influence the engine as much as good maintenance.
 
Personally I would never (again) LPG any 94mm bore Rover V8 having suffered liner slippage on a 3.9 several years ago. I now stick to the venerable 3.5's (no use I know to P38 owners) as RV8's run hot enough combustion chamber temperatures anyway.

This may be the case but the 4.6 seems to go bang whether on LPG or plain old petrol.

162000 miles lpg (single point)in 2003..... seems okay..... as okay as a P38 is.

As said luck of the draw seems to be the deciding factor.
 
i had a cracked block last year no lpg only had 90 on the clock but all is good now new engine to go with everything else that i have relaced this year, not the cheepest car i have had but what a car when its running well..
 
Mine is closing in on 140K and the wife's is on 120K. I'm a bit like #Fortgrange insofar as I am OCD with the coolant. Neither run LPG and neither have had cracked blocks (I'm sitting on a solid wooden chair as I type this). The problem I have is that I am not convinced you can completely avoid the cracked block thing even with good maintenance. Don't see the point in meeting the devil halfway hence the maintenance.
When you read posts from guys like #Jamesmartin you realise that cracked blocks are common but not always noticeable. Check out the recent post which polled to see what mileage people had got out of theirs - not many even got close to 200k.

ditto!
 
well just taken the engine out yesterday after removing the heads and finding nothing to write about

back in to work later today to pressure test the block !!

only had this rangy about 3 months and only because it had paperwork for a new engine 3k ago !

looking at the engine its a landrover replacement bottom end with no sign of wear at all but its got blue spots of paint on it so i have been told thats the grade 3 quality one ! nice

well been phoning around about having it top hat linered but its not to good due to being xmas week.

if it wasnt for the fact that the cars very tydy and i have sorted nearly everything else on it i would of put a match to it lol
 
gread 3 being the ****ist one? makes you wonder how they are allowed to sell anything that isnt grade 1 really :doh:
 
whats the grading ,the only grading ive know of is that blocks are graded by bore diameter so pistons can be matched at factory ,std factory pistons come in several sizes
 
at 102k i noticed pressure on the rad pipes and a heart sinking hiss when i opened the rad cap when cold:eek:
put a bottle of halfords block sealer in to try and prolong the inevitable and every thing went back to normal:D ran like this fine untill some **** nicked it and burned it out at around 111k:mad:
according to halfords though once its sealed its garanteed for life
im so glad i did it this way insted of paying £££ for a repair then it getting torched less than a year later

had a good long chat with a friend of a friend this morning whos in to drag racing, he seams to know his stuff, hes ex landrover engine plant.

he told me the specs on 3 colour codes on the blocks and shown me some he had about his work shop, you can clearly see the quality differance between them !

he uses only the red ones now with the top hat liners from the states, the same ones turners use
 
Anyway iam sitting here at work after just pressure testing my block ! and yes its leeking from liner 6 ! great so after stripping my nice clean as new, well 3356mile replacement landrover engine iam now looking at who to use for the liners as theres so many different oppinions !

and looking through my range rovers pile of history this is the SECOND engine ! it had a bottom end about 20k before ! its only done 128000 anyway
 
My previous '98 4.6 suffered terminal slipped liner at 109k miles, I replaced the short block myself with a brand new item, had I known better I'd have sourced a top hat type. Total cost considering I did all the work myself was about £3k.

My current '99 4.6 had a replacement top hat short block at 89k miles, previous to my ownership, but the receipt was for £4.2k :eek: Currently has 137k on the clock........
 
Fellas, you really are talking my P38 in to the classifieds with all this doom and gloom!!

Reverse psychology, glass half full and all that. Anybody on here have a P38 they've owned since nearly new, done over 150K miles and all they've done is change the oil lol.
