My lt230 is blowing liquid oil out the exhaust. The cylinder and rings are in good shape (rings are new) but it still blows out oil. I am going to replace the valve seals next. Anyone have any other suggestions?

Hey tom,
Would be a good idea to replace the valve guides...but one other thing that popped into my head...under the head bolts there is a washer...there are 2 copper washers and 2 steal washers. They have to be on the right stud when the head is bolted back down or it will cause a bad oil leak into the cylinder...that sounds like it could be your problem. Hope that helped[img]i/expressions/face-icon-small-smile.gif[/img]

Had the same problem on my 86 LT230. It smoked VERY badly all of a sudden and got worse as I rode it. I put in a new piston/ring kit and had the head redone {valve job} at the local machine shop. I put all new seals and washers everywhere and put it back together by the book. It worked perfectly, but I don't know what actually was causing the smoke. I suspect the top end {valve seals and/or guides} as the piston/ring/jug looked real good when I tore it down. It is a fairly easy engine to work on an the whole job cost me less than $150 with me doing the assembly. If you don't feel like tearing down the cylinder, just do the head. It would only cost you a head gasket to redo it. Also get some of the Suzuki black silicone sealer for reassembly, it is terrific stuff!

 

I’ve already tore down the jug. I put in new rings and everything is within specs now but it still smokes.

SMS069 may have it figured. I didn’t notice the washers were different before.

Thanks for your replies

 

BTW, I’m also replacing the valve guides. I wasn’t going to, but the outstanding dealership I get most of my parts from sent me the guides instead of the seals (thought that was awful expensive for valve seals) so I kept them also.

 

any way to get more information about the misplaced washers on the head bolts? What is the correct way those washers need to be and will I need to change the head gasket?

 

take advise from someone who has had a 230.

just go ahead and replace everything

doing it one part at a time, it is gareenteed, to keep smoking, i am telling you just get the valves done, and the cyclinder bored, and it will stop, its when you replace it piece by piece it starts to have problems.

He already has replaced everything but the valves. The 230 doesn't need any special consideration. You can easily just replace a single component in the top end and not have any more problems for years.
