Cost to Overhaul
My compression is low and after motor gets warm I hear some clatter that don't sound right and so I am thinking about an engine overhaul. But before I take it in to my local guy I am wondering what is a "normal" overhaul cost. I mean new rings (hone cylinders) and bearings thru out and a new oil pump. When cold my oil PSI is around 50 but when it gets hot it drops to around 5 psi at idle and 20 PSI at driving speed, say 2000 RPMs. Does this sound like an overhaul is warranted? Thanks

Re: Cost to Overhaul
I was suggesting that maybe you just need to adjust the valves, and not a total rebuild.
Maybe a neighbor kid would be willing to learn something while you talk him through it. |

Re: Cost to Overhaul
There are a few options. To obtain a rebuild kit is around 350 ish bucks. Shop fees to hone the cyls are totally dependent on your area, mine ran 40 bucks. The engine is not really that heavy, and you could solicit a neighbor to help lift it out of the compartment. Now if you want to do a drop in replacement, you could look into CT Rebuilds. For around 650-700 you can get a nice more powerful rebuilt engine and just drop it in. Use the search feature to look for the contact info for them.
Before you do any of that, I would do as suggested and adjust your valves which wont take you more than about 20 mins. |

Definitely try adjusting the valves first. The intake valves on these engines are made of a softer metal and are notorious for wearing down and sucking up into the head. If there is minimal wear, adjusting the valves will buy you some time. If there is a lot of wear (you will be able to tell by how much adjustment is required) they will need to be replaced. I have a lot of experience with these engines. If the valves have excessive wear, so do the cylinders. You might see crosshatching in the cylinder walls but don't be fooled. They are out of spec. Check them with a bore gauge. You will find the most wear where the rings set in the tdc position and where the combustion takes place. So......
Try adjusting the valves first. If that works, great. If not, I recommend a complete rebuild and that will run you about 600. Ct rebuilds and I ( Motor City Rebuilds / ebay-clark2416) both sell on ebay. Beware of the guy from California selling on ebay. I believe he is doing a ring, gasket, paint job rebuild not a quality rebuild. Sent from my SM-G900P using Tapatalk |

Re check the comp once the valves are in spec.
