Backstory: I'm currently attending college and my parents are giving me their old zj to use as a daily driver for school. They have been sinking 2k-5k bucks a year into maintaining it for the last 5 years, so its relatively problem free. But two issues plague it that I wanted to ask about.
The first, the rough running, about 7 years back the dash coolant temp stopped working, 5 years back the thermostat broke, engine overheated, and the radiator popped the cap spilling coolant all over the engine. The receipt for the repairs lists a few things pertaining to that, first the third cylinder had a low compression (whatever that means...
), second the exhaust manifold was broken, and third the head gasket was damaged. The shop that did the work told them that it would be more expensive to replace it then to rebuild it, so either rebuild and run rough, or replace and run into thousands of dollars in cost. So I'm wondering if they might have been talking about the whole engine, but the service writer just wrote it down wrong.
The second is a simple and stupid one, I just had the tires replaced, and upgraded from 225/75/15 to LT235/75/15, now the tires aggressive tread just barely touches the control arm at the steering stop. I was going to replace the control arms anyway, and I'm wondering if the aftermarket controls arms might not rub? (Bushings are cracked and creaking, so I figure time to upgrade.)
(Note: Yes my parents still hold the title to this jeep, but we have an agreement in writing for its transfer once I graduate college, the reason is it wouldn't pass inspection at current, and its registered in Tennessee which is cheaper then Virginia.) (No emissions and no safety inspections in TN for the county its registered in.)
The tires are BFGoodrich all terrain T/A KO, I got em for 80 bucks off after the tire place couldn't count its inventory 3 times in a row.
) (I wanted destination A/T, but nowhere seems to have them, there on backorder on tirerack.)
Its an I6 95, stock, I'm looking to upgrade but first I want to fix up the suspension, if its rubber its cracked, engine mount was replaced at some point though. (Tire place took out most of my cash, 900 for 5 new tires, so I still have a budget of 500 or so.)
