Final Followup: I replaced all the exhaust valves with new and touched up the seats. Reassembled the engine using DNJ gasket set. The engine fired up way faster than I was expecting and had a perfect idle. Only squawk was a leaking injector o-ring which I addressed in another recent thread and...

Thanks for all the tips. I inspected the fuel rail and did see a tiny bit off rubber stuck to the side. I swabbed it clean. I also installed four new Felpro o-rings which I lubed with a tiny bit of di-electric grease. Reinstalled everything and no more leaks. Not sure what fixed the leak since I...

I could use some advice please. 2.7L with 230,000 miles. I reinstalled the head after an exhaust valve replacement which I did all the work myself. I purchased a DNJ gasket set for the job. All went back together nicely and the engine fired right up with no miss. After the test drive, I popped...

Another update: I removed the exhaust valves and the one is burnt bad enough you can see it with the eye. A couple of others are burnt also, but barely. The seats are ok. I am going to replace all the exhaust valves with new and do a valve job myself. I looked and only tool I'm missing is the...

Update: I removed the head and found one of the exhaust valves in cylinder #3 was setting lower into the seat than any of the others. Here are a couple of photos of the work. This shows cylinder number three, and you can see the exhaust valve (lower left) is sitting lower than it should. Not...

Here's the followup: So I turned over the engine with all four plugs removed. I watched the cam lobe on the two intake & exhaust valves for cylinder #3. Got the lobes so they are pointing up away from the lifters, thus all valves closed. I measured the clearances and my thinnest gauge of .001...

Yes, I agree 3 of the four are low. There is no smoke at all. Car runs clean so I'm guessing it is valves. What is my next step?

Got a super deal on a 99 runner with 225k miles. It has the 4 cylinder (2.7L) engine and is 2wd. I think I got it so cheap because it is hard to start and when it finally does start, the idle is low and the engine shakes. I figured I could fix whatever the issue is, so here goes. First off I...

Thanks for the info. Keep us posted.

Did a compression test. :sobbing: Not good news on #3 at 70 lbs.

Thanks Red, I tried to post a new thread and still not able to.:sobbing: I have excellent mechanical abilities and I did not find any leaks yet. Will keep searching. One thing that bothers me, and again I apologize to the original poster for the thread hijack, but when I look at the rpms...

Awesome deal. Thanks for your service.

welcome.

Good deal by me...

Very nice!
