Hi all,
got a problem i need your help with, as you all know i'm about as technically minded as a fish, actually a blind fish, actually a dead and blind fish, so no laughing at my posting, ok!??

for a while i've had a small oil leak, if you are facing the engine, it appears to be coming from the cam cover, front left corner, the oil then drips down the left hand side of the engine and then collects on the plastic under engine tray. Had the gasket seal thing replaced a few months ago and this appearded to have minimised, if not cured the leak. last week at my 60,000 sevice at mango's they said there was oil in the plugs so replaced the gasket again, over the last week since the service i actually noticed oil on the ground under the car- not too much but enough to worry me, checked the oil level and this is at maximum and no oil warning lights have come on. the problem is i'm bloody 155 miles from mango's and my local perrys dealer will definitey screw me over for any work i have done. my plan is to keep a close eye on things unitl i get back to mango's again.

i'm scared incase the engine seizes on me...
why has the gasket replacement made things worse, did they over fill the engine, is there now more oil in the plugs so knackering my brand new spark plugs...

help me guys......

regards, raj :mad: :rolleyes: :eek: frown

Raj,
Don't worry mate... nothing serious!!!
From what you describe it appears to be a cam-cover leak. Since you have a 155 this should be an Aluminium one with the writing painted in red, right?
Ok, these things are very fragile since Alfa Romeo didn't do their homework (once again!!!); if you overtighten the cover by even a little bit you will crack the edges of it enough to promote a leak. These covers are around £160 new so what I would suggest is to buy a 2nd hand 156 black plastic cam-cover (comes with gasket but make sure to get the screws with it since these are different).
The only tricky bit is to find new hoses for the oil recirculation pipes to fit to the new cover since these are in different positions to the old one. My advice is to get hold of 156 hoses (brand new these are only £10 together I think) and modify away. I've made my own in a different way but that's because I work for a motor company so I had an entire parts-bin to play with :D
If you want to know more about this mod you should ask HENRY YORKE in this forum since he has done the same to his 155. Your bracket where the spark-plug coil packs are fitted to will fit on this but expect a slight clash with one of the screws on the cover (don't worry about this, ok?).
If you're bothered about the looks you can get hold of the beauty cover to fit on top of this which will make your engine bay look MINT!!!
This cover though requires slight modifying at the rear Rh side due to the position of the oil recirculation pipes (these will clash with the cover). Get hold of a Stanley knife and cut away!!! use some sand-paper to round/smooth off everything since you don't want to cut these pipes or they'll mess up all your hard work.

All in all this mod should not cost you more than £50 all in if you're prepared to do some of the work yourself.

Good luck,

TAZ.

Sorry,
Nearly forgot to tell you that, if you purchase a second-hand cover, make sure the fitted gaskets are not cut/split. Also, clean these with brake cleaner first to get all the crap off them, let them dry and then run over them with a finger dabbed in oil to lubricate them prior to installation.

I also assume you have a 155 2.0L 16V because this mod won't work on an 8V.

Regards,

TAZ.

Henry did this conversion on his no.10 car(RIP).
(Have you got a foto of it to post here or shall we visit your site...........?)

Also had this problem on my twinny, leaked into the plug recesses and caused a few probs, replaced the gasket and ......no fix!!!(did reduce it a bit tho')

Sounds like the 156 cover is the way to go.

Hi again Taz and Wrinx,

last night i parked the car in my garage with a fresh sheet of cardboard underneath. this morning when i went to look how much of a 'leak' there was, i reckon there was about 10mls of fluid on the board, it was oil stained but most of it was clear and water-like in nature, it refused to ignite so it wasn't petrol!!, anyway looking through 'tech room' and Mike Scarf mentioned undertrays getting full of oil when the filter gets changed, since i had a service last week i wonder wether this was the problem, so i'm gonna keep an eye on things.
do you agree???
regards, Raj
ps thanks for taking the time to reply.

Hi Raj

I'd have thought the garage would have removed the undertray to gain better access.......but then again!!!

I would expect a decent garage to not let oil get onto the undertray, but you never know. Is it still dripping off?
You could always remove the undertray to get a better look yourself where the oil is coming from if it doesn't stop. :D

Raj,
I'm not too sure about this one since I have given up on undertrays because where I live (lost one too many on speed ramps.. let alone denting rear silencers :mad: ). 155s are also renowned for having not very good gearbox gaskets; I know for a fact that mine is weeping just slightly but it really isn't worth changing until I'll get round to replace the clutch. PS 10ml does sound a lot!!!
I never experienced oil leaks after changing a filter (guess I do a proper job unlike main dealers!!!); it is worth taking the undertray off, give it a good clean, leave it for a day or so and take it off to check it again (ps don't drive around in the rain though!!!). If you still require to drive around then I suggest removing the tray and parking your car overnight with the cardboard underneath.
The morning after, take note in which way it was under the car, that way, if there is oil on it you should be able to trace it back if you pop your head under the car.

Just an afterthought.. it could be the leak from the split cam cover; this usually trickles all the way down the block to the oil cooler assembly if I remember correctly.

Good luck.

TAZ.

Hi Guys,

did a bit more investigating today. Left car overnight again and by the morning was again about 10 mls of water like fluid on the cardboard and oil stained.
The oil is dripping down from the cam cover front left [opposite side to battery] edge, it then hits a pipe coming from the water reservoir thingy and drips off a steel clip onto the plastic tray. Today there was a pool of oil big enough to warrant kitchen towel cleansing! I put a fresh sheet of towel and waited for a drip after a short drive, with the engine off the first drop hit the towel after about 20 secs,very clean oil as service less than two weeks ago. With the engine running the drips seem to slow substantially, checking the oil level [obsessionally] and it appears to be more than enough and no oil warning lights yet. No time to go to Mango's - whatever they did when they changed the gasket made a trivial problem a significant one- and my local Perry's are about as trustworthy as a Time share offer. Heard a few good things about SGT so will be going there asap, I know you boys have the ability to have a decent go yourselves but these are skills I simply do not possess!! No local specialists either who I have formed a bond with.

Taz, I think it is the cam cover.

thanks for all your advice, I'll keep you posted.

regards, Raj

ps Mobil 1 at the ready in the boot! :rolleyes:

hi there i too had the old drippy cam cover and the local alfa dealer told me to put it back on with some silicone compound i did this and ok for about a year, but it started leaking again but this time round i used a new gasket with no sealant and its been great so far i think too many people are useing to much pressure to tighten cover down the gaskett from cubleys in ainsdale merseyside were only about a tenner for the large and small together and is a very easy job to do ,alfa dealer wanted £18 just for one gaskett when i asked cubleys about diff in price they said they use alfa price disk so dont know why they are so dear maybe making money on the side but i definatley would do this job yourself as i am not a mechanic and do all i can myself like exhuast wishbones gasketts its just a case of off with the old on with the new good luk
