FINALLY!! sorry guys, ive been out of touch. ive been paying closer attention to my LUV truck than the wife's metro. I spent some time with the car today. and after running some seafoam again, i decided to take off the valve cover. an initial inspection doesnt show anything out of the ordinary, but once i tried to find the source of the ticking noise, i found that what i think is the number 2 exhaust valve is not contacting the cam rocker completely and therefore is tapping against the rocker itself. I tried uploading a video to youtube, but i couldn't get it to work properly. Is a complete cylinder head rebuild in order, or can i just take the one valve out to repair it? PS, this might be relevant, but i have noticed that the engine is starting to use oil. not only that, but my wife was driving the damn thing with it low almost 2 quarts of oil!! |

if you press the cam follower / rocker down against the valve when the cam lobe is facing away from the cam follower / rocker arm pad does the lifter collapse ? or is there slop there ? lifter should not collapse and there should be zero felt free play does problem go away when the oil level is correct ? ................................................... do you live near eagle mountain ? |

Included inside the part of the rocker you have your thumb on is a tiny, tiny hydraulic adjuster, prone to sticking and gumming up. Mwebb brings up a good point, if the oil was low, the lifter might have collapsed due to poor oil supply. Fill it up with nothing thicker than 5W-30 synthetic and drive it for a while to see if it clears up. If it's burning oil, then it most likely needs rings and a head job. |

well, i didnt sleep more than a few hours last night. im guessing it's because i went to bed mad, but anyway... Went out there this morning and removed the exhaust rocker rail and took a closer look, and sure enough the no 2 exhaust....uh.....adjuster is stuck. im going to dip it in some brake parts cleaner and see if i cant get it loose. ![]() ![]() Is there any way to remove this adjuster? or would i have to replace the entire arm. ALSO, just because im a dumbass apparently, im not seeing any lifters on my engine. i was under the impression that the lifters would drive a pushrod to open and close valves, but this engine has OHC. so what gives? anyone care to set me straight? ![]() To answer your question Web, im about 20 some miles NORTH of Eagle Mountain. I actually live in West Valley City, which is about 6 miles from downtown SLC. Woodie, the engine does have 184+ thousand miles on it. It may be time for a rebuild, but if i can put it off for just a few more weeks.... |

thanks. im a photographer by trade. So, i went to checker, and turns out the lifters listed in their system are exactly those that im having the problems with. so instead of paying the 150 bucks and waiting for 5 days, im going to soak them in some brake parts cleaner, and prime them with fresh oil. hopefully, this will work for the time being. I'll keep you guys posted! |

ok. so after putting everything back together, it seems like i might have messed something else up. Once i got both rails back on, and the cover on, im getting a LOUDER tapping sound. but this time, it sounds like all of the lifters are tapping against the valves. Im not sure if i missed a step, or if cleaning out the lifters caused this. ill see if i cant take a video and post it on youtube. maybe it will work this time... |

you should consider switching to synthetic 5w30 with European specification ACEA A3 B3 - B4 so that you do not repeat this and other similar exercises in the future , again. |

Good pics. This is my first look inside one of the 4cyl engines. If you look at your rocker, its roller tipped. That roller runs on top of the cam lobe. With the OHC design, no push rods. Hot Rodders pay a lot of money for a set of roller rockers. Not sure what is the flaw with this design. But with 180k+. Not to shabby. Hope this explaination helps. |

Rollers are nice, lifters are a disaster. The lifters in the three cylinder had a tendency to get gummed up and cause trouble and they were five times the size of these. The 16V head that came after has old fashioned manual adjusters that don't seem to ever need adjusting. I'd like the manual adjusters with the rollers, but you can't have everything. The other problem is that where the rocker is spring loaded against the "tower" portion of the head casting it sometimes wears, allowing the rocker to move over on the shaft until the oil supply holes no longer line up. Once that happens the roller stops turning and tears up the rocker and the cam. Yours look brilliant with quite a lot of miles so maybe the ones that do this have had crappy oil or something. |

When I was playing with the Toyota 2TC motors they were push rod engines. The rocker assy were just like these. But an older design. They used a hardend washer between the rockers and the aluminum spacers. We never had a problem with this wearing out the arms. I was running them over 8k rpm. Maybe the engineers forgot this lesson. And your right, these look great, not like the ones on a thread a few months back. |
