Hi everyone. Some serious help and advice needed re: oil leak on my 307 CC with the EW10A engine.
So a few months ago, my mechanic thought the leak was coming from the valve / rocker covers gaskets. So, I then purchased new gaskets from AliExpress, and then was advised not to replace just the gaskets but also the covers as well at the same time. Anyhow, I then went and purchased brand new covers as well.
Now they were fitted by my ever so reliable mechanic yesterday. He then told me to take the car home and do another full degrease, and take the car for another run and check for leaks. Well I did this, and still leaking, and the leak is getting really bad now. My mechanic topped up the oil yesterday, and with a distance of 100kms driven since he had it yesterday, it is now almost halfway down on the dipstick. That means almost 500ml of oil in 100kms.
So been back to the mechanic today. He put it up on the hoist, and even with the engine running, we can not see where exactly the oil leak is coming from. It does not appear to be coming now from the covers, BUT we suspect it is leaking from the camshaft housing where it meets the head. He has asked me to ask around, and see if this is an issue in the past for anyone else with the 307 EW10A engine.
If so, do we need just new housing gaskets, or will we need brand new housings, or can the housings be shaved.......we thought that shaving them may not be an option.
Anyhow, we have decided that it is not best to drive the car anymore, until the car can be booked back in to dismantle the covers, cams and housings. I dont even know if I can buy new housings and gaskets, yet to do research on that. But he thinks the leak is from exhaust level and above. I am also thinking, that if the car is stripped down that far, that I may as well just go that bit further and remove the head and put a new head gasket in, as it would be terrible to have to replace a head gasket in a a year or 2 when we were so close to have replaced it now at this same time. Please anyone on here, with mechanical knowledge for advice and help. I am not asking for myself, but for my wonderful qualified mechanics, here in Tasmania. Peugeots are not a car that they normally work on, but are willing to go all out and get my car fixed, as they see that I love my car, by the condition it always goes to them in....always fully detailed, and cared for like a baby.
Now further on after doing a little research this is what I have found. Firstly, there are people in the UK, that have had leaks from the camshaft carriers/ housings. And has been known of more than just a few people that have had the issue. Mind you have not seen any post anywhere that people in Australia as having this issue. I have also not been able to find that these housings to be available to purchase anywhere, apart from maybe Peugeot Dealers. I also have been unable to find a pair of gaskets that go between the housings and the head. Even complete engine gasket kits, do not show such gaskets; and therefore maybe they are bed down onto high temp RTV gasket silicone. One place in the UK bed them back down on the silicone. Also from another forum here in Australia a mechanic has said that they do leak and to bed hem back down with Permatex. So, from this, my guess is, that it would not matter if the housings were slightly warped, as silicone should over come this issue.......I hope. So, unless I hear anything else on the next few days, I will go back to my mechanic with this info. Also thinking that maybe removing the head to do head gasket just may not be a great idea. As it will need removal of exhaust and exhaust manifold, and the fuel injection and inlet manifold. These removals may cause other issues, and could then open up a can of worms. So, I am thinking, I get my mechanic to do a compression test on all 4 cylinders, and if they return reasonable good numbers, then we leave the head intact..........................................ANY ADVICE welcomed.
