| Re: Preventative Maintenance ADD YOUR TIPS!
I also have a K&N cone filter. definatly worth it. My caddy is more responsive. Also I read a couple posts in here of members not changing their oil until about 6-8K or so. Even tho it may be a synthetic oil it can still build up sludge and carbon and that will clog up the pcv system or breather system. This will cause the valve gaskets to leak. I cleaned mine just recently and then re-tightened the bolts on the valve covers and my oil leak and smell of burning oil that I've had for about 20k miles, went away. It's very easy to do. But it takes a hell of a lot of carb cleaner!!! |
