    Icon13 Cracked Sump

    Hey guys

    I found out why i was loosing so much oil. I have a cracked sump . One of the bolts holding the a/c compressor had come loose and out a great deal of strain on the other bolt holding it on and cause the sump to crack. I have 2 options:

    1. source a new sump.
    2. Find a place that does aliminuim welding.

    Does anyone have any pointers on where to find someone or recomend someone who can weld aliminum. Or does someone have a spare/second hand sump for an XU9J4 that they are willing to sell?

    Cheers

    Not sure if they are the same but I have a sump from a 94 405 SRDT that has been welded up sitting in the shed. They sit very low and are very vunerable to damage.

    Neil,

    I would be surprised if the sump off a turbo diesel would fit although it has to be worth a look as these share the same clutch and clutch cable so who knows.
    I reckon you'd have about as much chance of finding a second hand one as you would of finding life on Mars. The early ones overseas without air/con had a pressed steel sump and anyone wanting to fit air/con over there often have to buy the entire mechanicals just to access a sump. To freight one over even if you were given one would be a scarey price.
    Find any aluminium welder; someone who does TIG welding would handle it no trouble.
    My son had an aluminium radiator made up here a couple of years ago & he & one of his mates just made up & welded header tank and fittings on using a TIG.
    These days with alloy heads and blocks, a lot of engine rebuilders use aluminium welding as part of their job and if they don't they usually have someone they send their work to as they are having to get cracks welded and corrosion built of and machined off all the time.
    It can be done quite successfully but if you price a new sump, do tell us what you get quoted...

    If it ain't broke, use a 12" shifter.....that usually does the trick!!

    I would doubt it very much. My guess is that any aftermarket one would be less the air/con compressor mounts so I expect genuine & from a dealer such as Continentals would be the go.
    I'd suggest asking a Pug dealer for a comparison price; sometimes that can be an interesting comparison also.

    Many thanks for your genorosity. I have sourced a sump and reco a/c compressor orf a 92 TZi for 250 bucks. I thought this was good as my a/c compreszsor is screwed and it leaked all the gas after i had it regassed. Didnt really worry at first as its winter and i wont need a/c but for 250 i thought it was sweet. If anyone is looking for a spare sump to repair PM me!

    Hey Sproose,

    has your 'specialist' done any work on the car recently in the area of the air-conditioner If so I strongly suggest you forward the bill for the cracked sump to them as they obviously didn't bother to tighten the air-conditioner pump... Betcha they left the top two bolts finger tight as there a bugger to get access to

    Out of curiosity, have you had a price to have it fitted yet?

    Default Temporary sump repair

    A friend cracked the sump of his 405 SRDT about 18 months to 2 years ago. (Or rather, his wife cracked it for him). Rather than get it towed he tried the following.
    Jacked up the front for access and better draining.
    Drained the last of the oil.
    Gouged the crack to widened the exposed portion slightly.
    Syringed acetone repeated into the crack and wiped it down.
    Applied Sikaflex polyurethane adhesive/sealant into the crack and across the surface nearby.

    It was so successful, the replacement sump hasn't been installed yet. Too much trouble.

    That is particlularly cheap seeing as they'll have to purge the system to swap over the compressor and fit a new filter dryer and then recharge it with gas as well as doing an oil change on the compressor.
    You're basically getting the parts & labour for nothing as I'd reckon the air/con swap & associated work alone would top $250

    I've seen that done with a Renault 16 too. Crack due to AC compressor mounting. Very successful repair.

    Amazing stuff, Sikaflex. This was a roadside repair that was intended to be temporary to get the car home. I suspect that an even better, permanent repair could be done by bonding a thin aluminium plate across the bottom of the sump, if the surface is flat. BTW the syringing was carried out with the needle in place in order to get a fine high-pressure jet right into the crack.

    OK

    I have got the new sump on, havent got any pics on my website for it, all that happened was: The bottom mount for the A/C compressor cracked and started a very fine hairline fracture down the side of the sump, this is why i kept finding more and more oil each day as the fracture got bigger. All is good now! Comming up soon will be a reground inlet cam from the very respected PeterT and new oxygen sensor. Then save save save for an ECU.

    Take care guys.
