loks Posted January 27, 2012 Share Posted January 27, 2012 A problem on the Aristo but hopefully the engine is similar enough for an answer from you guys. Is it normal for there to be a bubbling noise coming from the "rocker box" (correct name eludes name at the moment) when you remove the filler cap? The oil was on the low side but I filled it to the dipstick mid level point and the bubbling noise was still there. I have never heard this before and neither of the oil warning lights have come on at all. The car seem to run OK. What could be the possible problem, is it because the engine was cold or am I worried about nothing and it is normal? Had to scoot of to work, so didn't have a chance to check it again when the engine was fully warm. Thanks for any help. Loks Link to comment Share on other sites More sharing options...

d-_-b Posted January 27, 2012 Share Posted January 27, 2012 Have you checked the coolant level? (just as a step towards ruling out the engine getting way to hot and starting to 'boil' the engine oil) Link to comment Share on other sites More sharing options...
Tyson Posted January 27, 2012 Share Posted January 27, 2012 This might sound silly but could this not be trapped air escaping due to the oil getting low. Plus is it a wise idea to run the engine with the oil cap off? Link to comment Share on other sites More sharing options...

Yep thats pretty silly Mike and it shouldn't be a problem running it with the cap off, obviously while the cars stationary Link to comment Share on other sites More sharing options...
loks Posted January 27, 2012 Author Share Posted January 27, 2012 Phew, thx for that reassurance Dnk, I have been doing this to all my cars since longer than I can remember.... and that is quite a long time. Wish I understood more about cars than I actually do. Link to comment Share on other sites More sharing options...

loks Posted February 6, 2012 Author Share Posted February 6, 2012 Thanks for the reassurance and things seem to be OK with the engine BUT on a slightly different note my gearbox is resisting to change up now. I guess the 2 problems are not related? Link to comment Share on other sites More sharing options...
Benjy Posted February 6, 2012 Share Posted February 6, 2012 Wish I understood more about cars than I actually do. Please don't take this the wrong way, but I wish I knew more about flying a jumbo jet, but I don't, so I don't do it! Somebody who knows a little bit about cars is often worse than somebody that knows nothing at all. My sister let her boyfriends mate mess about with her Impreza. I've now rebuilt it. Also, what's the reason for running the car with the oil cap off? Under normal driving conditions the cap's screwed on so surely, unless you're diagnosing something like a crankcase breathing fault, there's no reason to do this?

loks Posted February 7, 2012 Author Share Posted February 7, 2012 I wasn't actually running the car with the oil cap off, I was just checking the state of gunge on the underside of the cap. That is when I noticed the bubbling type of noise. I may have to start another thread on the gearbox issue. That problem is getting worse. Link to comment Share on other sites More sharing options...
