MY FIRST Zed Posted November 18, 2022 Share Posted November 18, 2022 Hi I'm new to the z world. I just got a 2005 350z without doing much research into there problems... always been a dream car of mine.. but any way wend I cold start my car it's oil pressure is around 100 120 psi until it warms up then drops back to the middle... after driving about 15 to 20 min it drops close to like 30s... I'm sure this can't be normal Quote Link to comment Share on other sites More sharing options...
G1en Posted November 19, 2022 Share Posted November 19, 2022 That seems perfectly normal for me, very similar to mine, always sky high on a cold start. Once warm, idle is around 25-30 and should be around 60 at 2k revs in gear. Quote Link to comment Share on other sites More sharing options...

MY FIRST Zed Posted November 19, 2022 Author Share Posted November 19, 2022 ok so it should be fine that today at a red light it sat at like 10 to 15, it a low mile car so just dont want to mess things up. i just had an oil change and i know it leaks a little oil from the hose and from the oil pan gasket being bad... as long as i get those fixed then i should be alright? one more question, when should i change out the timing chain and guides, i heard it should be done after 100k? should i do it?

Andy_Muxlow Posted November 20, 2022 Share Posted November 20, 2022 Being the de engine variant that’s fine really. If it was the hr variant it would be a sign of galley gasket issues.
