Xander Posted April 25, 2005 Share Posted April 25, 2005 Hi, I recently started loosing oilpressure on my rebuild l28et. After removing the oilpan (I though it might be a loose oil pickup tube) I found that the inside of the oilpan that used to be black was now shiny metal. The paint chips where clogging up everything. I never painted the inside of the pan. It was the original nissan paint but still it peeled off. What could cause this to happen? After the first rebuild I used a very cheap 15w40 supermarket oil. I slowly drove the car for 500 km just to setup my megasquirt and to breakin everything nice and slowly. After that I switched to a semi synthetic 10w40.

frank280zx Posted April 25, 2005 Share Posted April 25, 2005 Xander did you clean the oilpan with something prior to install, like brakecleaner orso ? Quote Link to comment Share on other sites More sharing options...

Tony D Posted April 25, 2005 Share Posted April 25, 2005 was the inside of the pan painted at all? I think the last on I pulled was bare metal... In any case, the only paint I have ever used [/i]inside[/i] the engine peoper is Glyptal (red electrical insulating varnish). Google Glyptal, and you should find it. It is good for sealing up a freshly-hot-tanked engine block. Quote Link to comment Share on other sites More sharing options...
Xander Posted April 25, 2005 Author Share Posted April 25, 2005 I spoke to an engine builder today and he said that synthetic oil can do that to paint. Quote Link to comment Share on other sites More sharing options...
