Title: inlet manifold gasket
Post by: Zoe20 on 28 June 2013, 17:41:53
hi all, just wondered if someone could give me some advise please, i bought a omega 2.5 v6 3wks ago, for the first 50miles it ran fine, then started to lack power, ive taken the car back to where i got it, they mechanic said it wasnt the coil pack and that it was the plugs and leads, fair enough they have replaced them free of charge. rung them up yesterday and have been told that the car still lacks the power and the mechanic now says its the inlet manifold gasket. he started the work this morning but when i rang them up at 5pm the dealer said he was still on with the gasket. Now surely it doesnt take a day and half to replace this. When i ask if it could be the coil pack the mechanic said no as the eml wasnt on and the car when idling was smooth, also when revved slowly it was smooth, but harsh revving caused it to be rough.  the problem was it was down on a cylinder but when idling would pick it back up, start driving the car it would be running on 3 or 4 cylinder.  I have a feeling that ive been sold a dodgy car they knew something was wrong before i bought it. im at my wits end now, feel like asking tomorrow if its not running for my money back. if its running then asking them to put half towards the tax which runs out on sunday.  thanks in advance

Zoe

I have found on 2.5 v6 -if you run duff leads/plugs it will kill coilpack :'( As for inlet manifold leak :o thats new on me--and can remove inlet on v6 myself in about 30 mins-Although they say no codes-coil pack doesnt always throw one-in my experience-likely cause for losing power is blocked breathers-which if left will cause rocker covers to leak :'( and if not done correctly can cause more grief-

Inlet manifold gaskets are rubber on these engines and never need replacing.Soundsl ike he aint got a clue what hes doing to be honest. Could be coil pack,which is awkward to get at,so maybe has avoiding it. If a general lack of power at all times,it could be collapsed exhaust baffles which block the gasses from flowing out.This is quite a common problem on the v6 for some reason.
I have had it happen twice. Faulty coil pack wont bring EML on.
Hes either full of crap or clueless.

thanks, also (sorry to be a pain in the rear) but if its a blocked breather or baffler, would that cause the car to (no better word) squeal when driving passed 3000revs, its kind of like a metal grinding noise and the car to kangaroo when passed 25mph. dumb question but would the EGR have any part to play in lack of power.

Again thanks

Faulty coil pac will not bring rthe eml on but it will bring it up as a random misfire cyl xx, so it could be the coil pack. also if the plug wells are full of oil due to cam covers leaking oil this will fry the plug leads and cause missfire and lack of power. get the garage to read the codes and get a list from them and then post up the results on here and we can diagnos for you. dont lose heart it will be fine, but pls stop the garage replacing parts willy nilly untill you have the codes and diag from us

the squeal you on about could be the alternator tensioner pulley-it gets louder at higher revs-

Squeel past 3000 rpm is likley to be the power steering /aux belt, or one of the tensioners going bad. do you have any history as to when the CAM BELT , was replaced last,? as it must not excede 40,000 miles or 4 years whichever comes first.

there is no oil at all in the wells. there is no history with the car, only mot cert and the yr before one and log book, on log book there has been 1 owner from new (w reg and it was a lady) The deal is replace part free of charge to be honest i feel like asking for my money back now, i have only done 160miles in the car, i need a car to get back and forth to appointments. Ive seen a t reg omega 2.5 v6 estate that has tax and test till next year for only £350 it only has 85000 on the clock too. i feel like they are just fobbing me off now.

what i will tell you will upset many--v6 can be troublesome-and expensive-that is why there are quite a few out there that have basically been run into the ground-seem like bargains-but to put right can cost a fortune

get the car back from the clowns and pm elite pete/ jamesv6cdx/ darth/ and they will be able to sort the car properly, do not waste your money buying more trouble get this one sorted and you will be a happy omega owner.
these guys are trusted omega mechanics and will give you a better service and price than any garage can give. you need to get the Cam belt done asap as you have no history and if it fails it will mean extensive top end repairs.

As with any car/engine if it has been abused or not serviced properly it will be a pain in the rear, i have had my v6 almost 11 years and has never broken down on me or failed to start, but that does not mean i have not had to do bits here and there, but i service it every 5000 miles and dont drive it into the ground.
4 pots suffer with cam sensors and head gaskets, v 6's dont seem to suffer these but they do suffer with crank sensors so it is swings and roundabouts.

that is your miggy--however many out there are not looked after--If anything-better buying one on here-than anywhere else-as looked after---- I would have gladly checked car for Zoe20 but too far for me to be honest :'(
