[HTi]Johnson Posted April 19, 2005 Share Posted April 19, 2005 Yeah I started my car up today ...first I thought I was getting an exhaust leak...nope...it just got worse... So, I went to the store and got supplies for the oil change. But before I left,for the store, I put in a 1/2 qt of ATF...20 miles...and still noise.(That worked for me last time,MMO didn't.). SO I'm kinda thinking that my oil thinned out...way out... I bought Castrol High Mileage 15-40. Tomorrow I will do the change and report back... And would the T.O.D. mess with the knock sensor? Because the car's drivablilty sure did goto crap...it lugs in low rpms and kinda misses in high. I only posted this because this is the worst tick I have ever heard... 1987 GL-10 Turbo.

555Ron Posted April 19, 2005 Share Posted April 19, 2005 I'm no expert, but the TOD is just noisy lifters and a bad oil pump. It won't lose power if this is what is causing the noise. Perhaps its piston slap or something sinister like this... Link to comment Share on other sites More sharing options...
ausubaru92 Posted April 19, 2005 Share Posted April 19, 2005 Mine started the other day, only intermittent though, and usually after work (parked in sun for 8hrs) Is it because the oil pump is failing or is the mesh on the pickup is blocked?? Surely is must be doin engine damage:confused: Link to comment Share on other sites More sharing options...
[HTi]Johnson Posted April 19, 2005 Author Share Posted April 19, 2005 NO NO NOt piston slap...!! I was asking if it could lose power because the knock sensor could be sensing the massive tapping. And wouldn't bad lifters make it so the valves open later? THis is coming from one side also...the driver's. Link to comment Share on other sites More sharing options...
Ross Posted April 19, 2005 Share Posted April 19, 2005 The tapping will mean your valves are not opening as far or for as long. If its a big tap, then i would be surprised if you didn't notice some power loss. Dunno about the knock sensor, I think the tap wouldn't be "heavy" enough to effect it, but who knows?

[HTi]Johnson Posted April 20, 2005 Author Share Posted April 20, 2005 FIXED IT! That's right. No more T.O.D. I did an oil change...with 15x40w Castrol High Mileage and a new filter. with 1/4qt ATF. I drove it normal for about 10 miles. Then I got pissed when it didn't fix. SO I reamed on it...high RPMS....like 7000 to 7500. For about 1 mile. THen I putted around about 1/2 mile then reamed on it and it faded away. YES!! Link to comment Share on other sites More sharing options...
robaru Posted April 20, 2005 Share Posted April 20, 2005 Knock sensor retards timing 5 degrees if it senses knock if I remember reading correctly. I hope you cured the tick. I recently cured mine with a new seal kit for the oil pump. Mine would start to tick if I drove over 65 for awhile. I found that the oil seal was spinning with the rotor and would suck air when I got going fast enough. Strange. Link to comment Share on other sites More sharing options...
