Taggy Posted March 5, 2013 Share Posted March 5, 2013 I need to identify if a valve is fucked on my head and leaking exhaust gasses into the oil ways and not from the rings and via the sump, but i need to be able to look at to see which one its coming from, can i start the engine with the rocker off for a brief moment? Or will i literally get completly covered in oil Or is there an easier way to do it Quote Link to post Share on other sites
funny onion Posted March 5, 2013 Share Posted March 5, 2013 (edited) if i were you i'd give it a go briefly, don't imagine it's going to spray oil everywhere drastically. and if you do decide to do this, please take a video - you could take the head off and get it pressure tested at a machine shop. pain in the arse though.

TrisK Posted March 5, 2013 Share Posted March 5, 2013 I think itll probably mist oil overwhere, or like spatter it everywhere, rather than like pour out. Quote Link to post Share on other sites
russ78 Posted March 5, 2013 Share Posted March 5, 2013 Just an idea but put cling film over the top of the head that way you can still see what's happening but not make a complete mess if its only brief it shouldn't melt, Just a idea it might work ? Quote Link to post Share on other sites

turbo Grant Posted March 5, 2013 Share Posted March 5, 2013 Just start it up with the cover off, just stand to the side of it Quote Link to post Share on other sites
StuDoc 72 Posted March 5, 2013 Share Posted March 5, 2013 (edited) It will splatter everywhere, done it loads on different engines and the 4e cams are quite open to the elements lol. Take off the rocker and turn the bottom pully with a wheel bar. You will be able to see how much the valves are moving. Clockwise Obviously lol.

Taggy Posted March 5, 2013 Author Share Posted March 5, 2013 Yeah i only need to start it for abot 5 secconds, just so i can see if the valve is goosed or notlol ok maybe i will do that : Quote Link to post Share on other sites
StuDoc 72 Posted March 5, 2013 Share Posted March 5, 2013 Just turn it by hand then my friend. Will be far easier to see. Quote Link to post Share on other sites

Taggy Posted March 5, 2013 Author Share Posted March 5, 2013 Ill get a video of it later on, will go one of two ways Quote Link to post Share on other sites
DavidAshton Posted March 5, 2013 Share Posted March 5, 2013 Was going to say if you do it make sure you film it. I once left my oil cap off and drove 10 miles that made a right mess! Quote Link to post Share on other sites
Taggy Posted March 5, 2013 Author Share Posted March 5, 2013 yep done that too Quote Link to post Share on other sites
Driver Posted March 5, 2013 Share Posted March 5, 2013 (edited) Take your oil cap off and start the engine. Watch how much oil sprays about and then multiply it by about 30/40x for the increase surface area. Even 5 seconds will make a massive mess. Do it and video it so it can be saved on the internet for future generations to laugh at you. Edited March 5, 2013 by Driver Quote Link to post Share on other sites
Amjad Posted March 5, 2013 Share Posted March 5, 2013 I'd have thought it would have made a mess, leaving the oil cap off did for me lol Quote Link to post Share on other sites
