Hey there guys I’m recently rebuilding my 86 MJ. I need some Recommendations for quite a few stuff. 1st is I’m lifting my manche 4.5inches with 35 inch tires so I’m confused on the gearing issue and didn’t find anything on the forum. Is changing the gear ratio from 4.10 to 4.88 with these size tires work almost as it does now? And if not I know the Dana 30 can’t fit anything past 4.88 so what can I do or to get this done right the first time instead of putting in 4.88 ring and pinions for no reason. 2nd I’m having a bad leak from the Pcv valve and ventilation filter valve area. I also heard people having the same problem also but I bought a new valve cover/gasket with new pcv valves and vent filter with performance spark plugs and wire set. Will I come across this problem again with these new changes? This truck doesn’t seem to have engine or tranny problems and it shifts nice to 75mph pretty well for it’s age and mileage at 165000 on the odometer. Any other solutions to stop this bad leak? 3rd. Other changes I’m making is timing cover and seal/gasket, oil pan gasket, pinion seal/differential servicing, changing out old hoses and clamping them right. I feel like I’m missing something and I want to get it done in an timely matter. I’ve also notice alil leak from the tranny and gas dripping out of the fuel neck filler if I pump too fast. 4th. I know it’s not that big of a deal but I don’t want it to get me stuck on the road one day, the fuel level reading doesn’t work but goes to 1/4 on the reading on full. I don’t know what to do for this mishap, I don’t really see videos on what could be possibly be wrong. 5th. On the 4.5 inch lift kit it’s only offering leaf plates to put on the old leaf springs to use with it so I was wondering if this is alright if the leaf springs only have surface rust. I would also want recommendations before doing any lift work. I know this is a lot of questions for you guys but I love this truck already for it’s future potential(I got it 2 weeks ago) I’m upholstering the whole interior the way I like it and would also take exterior advice from you guys. I’m serious about rebuilding so let know about common mistakes
