patman Posted February 20, 2014 Share Posted February 20, 2014 Still in two minds about changing my piston rings while the head is off the car, after checking them Rob H did explain to me in this post which I posted up below.....http://www.ukstarletowners.com/topic/77037-piston-movement-in-bore/?fromsearch=1But I'm still in two minds about the whole thing maybe I should get a video up of the movement in the bore just in case it's normal but on the other hand if I do have to get a new ring set which are the best ones to get for standard size pistons, I can't see how the slight pistons movement in the bore isn't normal when compression test showed all good late 150's early 160's and engine was built last May.Thanks Pat Quote Link to post Share on other sites

Bussey Posted February 20, 2014 Share Posted February 20, 2014 Get a video up mate, would probably make it a lot easier Quote Link to post Share on other sites

funny onion Posted February 20, 2014 Share Posted February 20, 2014 Put Hastings rings in my gt engine. Been mapped up and driven away for a good 6 months+ now and compression is still moint etc. Quote Link to post Share on other sites
patman Posted February 20, 2014 Author Share Posted February 20, 2014 Thankyou for that info mate but am hoping they last for a good few years not hoping after 6 months they will need checking again? But I see where your coming from have you got a link aswell for them rings so I can have a look please. Quote Link to post Share on other sites
funny onion Posted February 20, 2014 Share Posted February 20, 2014 I'll try and find a link when I get in. Hastings have an awesome reputation as far as I could see when I was looking around. Had my bores honed too which if you're changing the rings is probably worth doing too. Quote Link to post Share on other sites
patman Posted February 20, 2014 Author Share Posted February 20, 2014 Yes I plan on doing all that mate but just need to see if the pistons do have movement or not and if they do how much not getting a lot of info about it at the moment Quote Link to post Share on other sites
AdamB Posted February 20, 2014 Share Posted February 20, 2014 OEM Toyota, or can't go wrong with Hastings, their a very good manufacturer. Quote Link to post Share on other sites
patman Posted February 20, 2014 Author Share Posted February 20, 2014 Can I ask (silly question) which is more likely to be stronger or be better or how much Bhp it can cope with etc sorry for the dumb questions at least when it's all done it will be a good strong engine that lasts Quote Link to post Share on other sites
AdamB Posted February 21, 2014 Share Posted February 21, 2014 Neither, it depends on many many factors, honing tolerence, ring gap, cross hatch angle blah blah, but it doesn't mean X is stronger than Y. All rings are put under tension against the cylinder wall, you will find the limits of the pistons before you have any ring seal problems. Quote Link to post Share on other sites
patman Posted February 21, 2014 Author Share Posted February 21, 2014 That's a very good answer thankyou Adam mate really appreciate it all I need now is the link to the rings I need the Hastings ones Quote Link to post Share on other sites
patman Posted February 23, 2014 Author Share Posted February 23, 2014 Been looking at these Hastings piston rings and you can get different strengths etc anyone know what the best one is to go for or just stick with the cast iron ones? also still waiting for that link please so to know the right ones to get.
