  3. Uncovering a Broken Lifter - Can I get some Advice?

    in Newbie Question and Answers

    Posted

    Ouch, that one looks pretty awful tom! Glad replacing those two are working out for you now.

     

    Replacing one rocker is just fine. No big deal replacing lifters, just be sure they are spongy, push paper clip in hole to bleed if hard, lube up with assembly lube and stick them in.

     

    Perfect, exactly what i needed to know. Thank you!

     

    Also figured I would do valve guide seals since I'm in there, what is the best way of going about that?

     

    I hear that there is a way to use compressed air to keep valves up and also a tool shaped somewhat like a "L" that you stick in the spark plug hole that also keeps them up. I would like to think that i could just use the tool that you put into the plug hole, as i do not have an air compressor yet. Also will need a valve spring compressing tool.

     

    Any recommendations or tips? This is my first time doing such a job and the last thing i want is a valve dropping down into the head...

  4. Uncovering a Broken Lifter - Can I get some Advice?

    Hello all, I have a stock engine that was rebuilt by Jasper engines about a decade ago by the PO.

     

    That being said, there has been some issues in the driveability of my quest recently and after servicing/replacing all the known major points of failure for our cars such as:

     

     

    - Fuel system (injectors, FPR, Fuel Pump, Fuel lines, Fuel filters, Throttle body "rebuild" w/ new gaskets, o-rings and all that jazz),

     

    - Electrical (Wiring, Relays, new Fusible links, injector clips, ISC/MPS, TPS, Grounding points, CTS, ECU)

     

    - Ignition (Servicing Dizzy and installing new Cap, rotor, Pick up Coil, vacuum advance, BUR7EA11 plugs, NGK plug wires, and Ignitor) 10* BTDC base timing

     

    - Emissions (Dad's Turbo PCV valve, New Vacuum hoses, o2 Sensor, EGR Delete)

     

    - Boost Leakdown test - passed

     

    - TPS, ISC reset

     

     

    I Have STILL been experiencing OCCASIONAL/INCONSISTENT issues while the engine is cold and warming and also issues when under boost - it feels like the turbo is working against the engine while under boost. I try not to dog the thing, but it is my means of transportation.

     

    So to cut to the chase I figured the next best place to look is something mechanically wrong with the engine. I have heard of issues with the Jet Valves and some problems they may cause - that was my prime suspect. Ordered a Jet Valve elimination kit that i had yet to install, so I figured I would knock another problem off the checklist Today.

     

    Off with the valvecover and the rocker assembly and voila! Removed the Jet Valves and put the Elimination plugs in their place.

     

    The Jet valves did not give any indication that they were failing, and looked pretty good IMO.

     

    While i was Inspecting the Lifters and Rockers I noticed one Lifter did not want to slide out of the Rocker very easily like the others, and here is why:

    I think its broken. haha ;)

     

    Now when inspecting the Inside of the Rocker, it looks like it has been beat up a little bit on the very edges, not exactly where the lifter sits (about the 11 to the 4 o'clock position in the picture) kind of a ring around where the lifter sits starting at (what i am hypothesizing) is the 2nd oil port on the side.

    It is brutally obvious that I will need a new lifter and probably a new rocker arm..

     

    It is the No.1 Cylinder Exhaust rocker.

     

    My questions are:

     

    1) Is it wise to just replace the one lifter? I am not doing anything with the cam - it will not be serviced/ replaced. Will replacing all of the lifters effect anything negatively? (I'm assuming not, but that is why I am asking) I am under the impression that hydraulic lifters are automatically adjusting and pretty forgiving - Ordered 8 new Hydro lifters from DAD today.

     

    2) Is replacing one rocker arm a good idea? or should all of them be replaced at the same time?

     

    I had not been expecting to run into this, I'm sure nobody ever does, but I am in unfamiliar territory and could use some guidance on how to proceed.

     

    Thanks for bearing with me!

    Appreciate the offer skullz! Very generous of you. I'm already settling up with a member here though.

     

    It's a PITA to get out if its connected to the wiring harness hah. If its just mounted to the pillar, and you have a sideways ratcheting screwdriver, may be able to get it out without much fuss.

    If the contacts just need cleaning they are easy to open up and service. Might be better than replacing with a 25+ year old one about to experience the same issue.

     

    Scott87star, maybe I read that too quickly and did not understand exactly what you were trying to get across... I apologize if I seemed oblivious.

     

    I was merely referring to the outermost fingers of the relay contacts being clean.

     

    Are you suggesting that there is a sound way of opening up the relay and repairing it?
