TimS Posted February 4, 2014 Share Posted February 4, 2014 Hi all, I'm running an hpi Baja 5b and have just replaced the stock exhaust with a clone version of the SS tuned exhaust. I took it out for a run and found oil leaking from between the cylinder head and the header pipe. I know I fitted the gasket, so my question is whether this is in any way normal with the SS tuned pipe (I did not have this issue with the stock exhaust), does it effect the performance in any way if I just leave it as it is etc. Any advice would be appreciated. Thanks, Tim. Quote Link to comment Share on other sites More sharing options...
Feedtheinferno Posted February 4, 2014 Share Posted February 4, 2014 (edited) Well when you say you fitted a gasket, did you fit a new one? Was it the correct gasket for the exhaust? What materiel was it made off? Edited February 4, 2014 by Feedtheinferno Quote Link to comment Share on other sites More sharing options...
53HRA Posted February 4, 2014 Share Posted February 4, 2014 Shouldnt be leaking mate,might be an air leak.Check the gasket or replace it Quote Link to comment Share on other sites More sharing options...
TimS Posted February 4, 2014 Author Share Posted February 4, 2014 Hiya, Thanks for your replies. I used one of the gaskets that came with the exhaust, which was exactly like the stock one I took out. From what your saying, I guess the only way forward is to replace it. Regards, Tim. Quote Link to comment Share on other sites More sharing options...
Feedtheinferno Posted February 4, 2014 Share Posted February 4, 2014 It wasn't copper was it? Quote Link to comment Share on other sites More sharing options...
TimS Posted February 4, 2014 Author Share Posted February 4, 2014 Hiya bud, No, I'm sure it's not copper. Regards, Tim. Quote Link to comment Share on other sites More sharing options...
Feedtheinferno Posted February 4, 2014 Share Posted February 4, 2014 OK well the next thing would be to check that you have tightened it up enough, also that there are no hairline cracks anywhere on the exhaust as that can cause a leak, Quote Link to comment Share on other sites More sharing options...

DARSKi-RC Posted February 4, 2014 Share Posted February 4, 2014 The exhaust header bolts need to be tightened right up. Probably more torque needed than 99% of the rest of the kit. The tiniest of air gaps will mess up your tuning, introduce bogging and leak oil on your brakes ;-)Oh and I went from the SS pipe to a clone Dominator (it also leaked first run until I cranked the bolts down some more) and the SS pipe is loud but average performance.

TimS Posted February 4, 2014 Author Share Posted February 4, 2014 Thanks darski-rc, I suspect you're right and the bolts need tightening - I just didn't want to admit it to myself and take everything apart to do it! Interesting what you say about the clone dom pipe though................ Quote Link to comment Share on other sites More sharing options...
spillidge Posted February 4, 2014 Share Posted February 4, 2014 It wasn't copper was it? Are copper gaskets no good ? Quote Link to comment Share on other sites More sharing options...
Feedtheinferno Posted February 4, 2014 Share Posted February 4, 2014 Are copper gaskets no good ? Honestly bud, no they seem to require more pressure in order to keep a good seal and that normally isn't the kind of pressure you would want to put on the item it is sealing. I'm sure we will get people on here disagreeing with me but from experience I found they always leak. Quote Link to comment Share on other sites More sharing options...

Guilty as charged will swap mine at weekend, thats probably where the oil is coming from thought it was head gasket, you learn something new every day, thanks for advice.

carsonkev Posted February 18, 2014 Share Posted February 18, 2014 Abit of hi temp silicone gasket does the trick use your gasket and run a bead of silicone round it then bolt it down works a treat You can get it from motor factors just rember to put the lid on properly there a pain in the a Quote Link to comment Share on other sites More sharing options...

Thunderwolf Posted February 18, 2014 Share Posted February 18, 2014 If you need to use silicone gasket to use a gasket you may aswell just use the silicone I got a copper gasket on my Baja, keep meaning to take it off and cut out a paper one out the gasket paper I bought months ago Quote Link to comment Share on other sites More sharing options...
Stoka Posted February 18, 2014 Share Posted February 18, 2014 I use this stuff on my exhaust & engine gaskets, zero leaks since using it; http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_173139_langId_-1_categoryId_255217 Quote Link to comment Share on other sites More sharing options...
