well afte 140,000 miles the kj looks like its due for some valve stem seals, getting a little puff of black/blue smoke on start up 
now my question to those that know, i have a bit of wrenching ability is this a job i could tackle by my self or should i just go to an engine shop and get them to do it i really dont want to take the heads of if i dont need to |

Well with the 3.7 being a SOHC engine that means the cam needs to come off,you'll need a valve spring compressor that does not require head removal and a air compressor with adapter to take place of the sparkplug to keep the valve in place when taking the spring keepers off.Might as well take it to a engine shop and have the heads rebuilt since if the valve seals are leaking then it's a good possibility that the valve guides are also worn and need to be replaced also.It's not a fun job being a SOHC engine and having the correct tools to deal with the cam chains is almost a must. |

Are you consuming oil?A little puff on start up isn't a big deal.Now if you're going through a quart of oil in 5-600 miles I'd fix it now. |

heh, thats nothing. Our corolla has been going through that much oil since it had 40,000miles! My jeep will never live up to that thing.
