Tristin Posted June 2, 2014 Report Share Posted June 2, 2014 I think I have a similar issue... I used to have my hood release cable wrapped up in my apron and it would sometime come loose under the car. I would have this weird noise that sounded like the cable touching my fan, but now that I have the cable in the right spot I know it's not touching the fan... Yet I still get that same sound intermittently. It's weird. Do your noise sound like something in the fan? Quote Link to comment
jrock4224 Posted June 2, 2014 Author Report Share Posted June 2, 2014 electric fans ..... i dunno its wierd ....... i sounds like loose parts in the oil pan ..... butu i can feel it in the floor so it makes me think its maybe exhaust ... gonna pull the valve cover see if i see anything Quote Link to comment
q-tip Posted June 2, 2014 Report Share Posted June 2, 2014 If you can feel it in the floor I would guess exhaust, mine rattled loose on my car and it sounded like the transmission was trying to come thru the tunnel Quote Link to comment
MicroMachinery Posted June 2, 2014 Report Share Posted June 2, 2014 I'm thinking detonation/pinging. Does it go away if you ease off the throttle? Quote Link to comment
jrock4224 Posted June 2, 2014 Author Report Share Posted June 2, 2014 i was thinking it might be the tranny too .... i dunno .... fuck i right its canby ... it will either make it or it wont ... i will try and see what the issue is before then but not hoping i find anything Quote Link to comment
jrock4224 Posted June 2, 2014 Author Report Share Posted June 2, 2014 yes its the loudest detonation ive ever heard but i have been using cheap 87 octane the last two times...im at about 9-10 degrees btdc.........since the over heating issues i have a dieseling that wasnt there before Quote Link to comment
q-tip Posted June 2, 2014 Report Share Posted June 2, 2014 Its the fuel if its dieseling as well as pinging Quote Link to comment
skyblue Posted June 2, 2014 Report Share Posted June 2, 2014 Yea run some premium and see if it still does it. Quote Link to comment
jrock4224 Posted June 2, 2014 Author Report Share Posted June 2, 2014 ok so where should i set the timing if im at 9-10 now and yes i will try better gas just being a cheap skate Quote Link to comment
skyblue Posted June 2, 2014 Report Share Posted June 2, 2014 Retard it a couple degrees at a time. So, go to 7-8 and check it. But the premium gas might be enough but then if that fixes it you will have to run premium all the time. Quote Link to comment
bananahamuck Posted June 2, 2014 Report Share Posted June 2, 2014 if you retard the timing to much not only will it run like shit,,, it will also run hotter,,, which in turn will make it ping if it gets to high. Quote Link to comment
q-tip Posted June 3, 2014 Report Share Posted June 3, 2014 Time it by ear, twist till she's smooth 2 Quote Link to comment
jrock4224 Posted June 4, 2014 Author Report Share Posted June 4, 2014 naner got me thinking ...... so i put more timing in it...upped to 12 degrees which is usually where i start my engines at .... runs smoother ..... runs cooler...(little not lots) and im lacking a little power in 5th in my 720 tranny and 3.88... but i leaned her out a little too when i did this so might try and fatten her back up a little see if that helps ... alsp plan to check the exhaust right now see if its hitting the floor Quote Link to comment
jrock4224 Posted June 6, 2014 Author Report Share Posted June 6, 2014 fucking exhaust .... l 16 and 388 and a truck 5sp is just gut less...( well only in 5th gear ) detonation fixed by advancing tuning and better fuel, it was minor the exhaust was most the noise again hitting the tranny tunnel Quote Link to comment
mrbigtanker Posted June 6, 2014 Report Share Posted June 6, 2014 Hey cheap skate run some race gas or at least 91 in that thing...lol 1 Quote Link to comment

That L20b/5spd conversion was the best upgrade I have ever made to a Datsun truck, the LZ23 I have was a great upgrade also from the L20b, but going from an L16 to a L20b was a dramatic difference, it made the truck awesome compared to before when I thought about getting rid of it. 1 Quote Link to comment
jrock4224 Posted June 9, 2014 Author Report Share Posted June 9, 2014 i had two l20 in this truck since the last l16... its temporary... 1 Quote Link to comment
