    Accidentally mixed grease. How much time do I have

    Did a front wheel bearing on my 300zx, and took me almost a week. One half of the new timken bearing fell out of the race. I wiped as much debris off, and because most of the grease was removed by this, I re-added some wheel bearing grease I had. I guess because it was early, I didn't realize...

    High deceleration vacuum, and how to reduce it

    I unknowingly purchased an oil burner when I purchased my 350z Rev-up. Faulty rings and design on the Rev-ups simply means you have to deal with it. Some owners have had up to 4 engines replaced by the dealer, and still burn oil. I burn 1 qt every 250-500 miles. It seems the burning stems from...

    My Mos2 story.

    I started using this in my Nissan 240sx years ago with no negative results. I picked up a Nissan 300zx Z32 twin turbo for dirt cheap. I didn't realize the oil pressure gauge wasn't faulty, and the 0 oil pressure was near accurate. Lest we forget I drove the car home in rush hour with not a drop...

    Did I get a used bottle of lubegard yellow?

    I had to hunt for a bottle of Lubegard gear supplement for my Nissan transmission. I've used them in a few transmissions before but I forgot what color the fluid is. When going to add the fluid, I noticed the metal seal wasn't fused to the bottle --I never had a seal just fall out with the cap...

    Found radiator cap was bad, damage?

    Bought a 350z a few days ago, drove fine but I really didn't give it a full 100% inspection before the purchase. Well I put about 200 miles on it, and a few redline bursts here and there. Tonight just for fun I decided to squeeze my upper radiator hose after a long 60 mile drive in about 90f...

    Anybody insulate their oil filter?

    Was wondering if anybody has made an oil filter cover out of some kind of heat reflective insulation? I bought some aluminum bubble insulation from home depot, cut a rectangle section to wrap my oil filter, and secured it with a T-clamp. Would seem it would be useful in the winter season to trap...

    Thin diff fluid in winter.

    Has anybody thinned their fluid in their open diff in arctic conditions? My winter beater only see's really cold weather, and I decided to thin the diff fluid slightly with MMO. Has anybody else done this on an OPEN differential?

    Cooler thin oil, or thicker hot oil?

    What is your guys input on oil diluted with MMO that is cooled via airflow, or thicker oil that is insulated to the airflow? On my Saab 9-5 the oil pan and filter (pl20195 later will be pl30001) is exposed below the undertray. The shape of the undertray almost directs airflow directly onto the...

    MMO and turbo's

    I have a saab 95 im trying to clean up. Lots of varnish, havent pulled the VC's but when I open the oil cap while the engine is idling, I can barely see any oil squirting up onto the cams. Its starting to make alot of valve train noise when cold, so I added 1qt mmo to 4 qts T6. Ive heard in...

    Dirt fell into spark plug hole.

    Today I was cleaning some things up on my truck, after I was done I changed the spark plugs. Well on the VG30I, dirt seems to accumulate in the spark plug tubes. Alot fell into one of the cylinders, along with a piece of plastic that was wedged in there. I tried to blow it out, but nothing came...

    Friction modifiers?

    Im using currently rotella T6 in my 240sx. Its not boosted, but it see's high loads. Ive been reading its lacking friction modifiers to be compatible with wet clutches. I do currently have a bottle of LM MoS2 in there, however would I be better off with something that has more friction...

    PL30001 for racing?

    I have a 240sx that takes a PL20195 (oversized). However I can get the PL30001 to fit by modifying the Oil pressure sending unit. This filter is almost 2x the size, however Im worried about oil pressure with such a massive filter. Im also worried about the gasket squeazing out because the...

    Engine bay, or radiator cooling?

    I've constructed a blockoff system for my radiator which I have been testing. I have a mishimoto radiator, no ac or fan shroud. The S14 has two large openings on the sides of the radiator which air can pass through into the engine bay. I sealed these two gaps off, which forces all air to go...

    Burning oil with SSO

    I think im burning SSO. I checked the level before going on a hard 45 minute run, and when I got back I was about 1/3rd qt low. Topped it off, and went for another run a few days later, same thing. Is the SSO maybe not the best option for heavy abuse?

    Remove primary o2?

    So on a pathfinder 1987, ive been able to get 21mpg with a vacuum leak and a PCV valve pulling unmetered air. Now with no vacuum leaks, PCV valve capped and all vents are VTA, im getting 8? So could possibly removing the o2 on a pre-OBD1 car have its advantages?

    Stored car outside, with no stabil.

    Has anyone ever stored a vehicle outside with 10% ethanol gas, without adding any stabilizers too it? I had a very small amount of MMO in the gas tank, but nothing else. Im mainly concerned about the freezing and rusting of the fuel lines. Its been about 6 months since ive started the car, and...

    Oil weight for high rpm's?

    On my Nissan 240sx with the Ka24de engine, the reccomended weight is 5w30. However the FSM states if 5/10w30 is not available, I can use a higher weight. I was thinking maybe for higher rpm protection maybe a 0w40 or 5w40? Currently using amsoil 5w30, but havent been racing the engine on that...

    Dex III & Friction Modifiers

    My old 87 nissan pathfinder calls for Dex III. Not matic-d. I assume its just pure DexIII. However I would like the benifit of synthetic, and am using a few qts of Valvoline Maxlife HM. The Maxlife says it contains friction modifiers, which I how much modifiers I dont know. Does all standard...

    Flushing trans question.

    So Ive read your supposed to add the same ammount of ATF as the trans expels. I dont think that is physically possible IMO. SO I was wondering can you just pull off the cooler line, and drain all of the capacity (in small increments), and then refill? Or will this burn out the pump? I wouldnt...

    Remove internal filter in favor of remote setup?

    I just got my B&M remote tranny filter and external oil cooler setup in the mail, and I was wondering about the internal filter. Has anyone actually removed this internal filter completly and just used an external filter? It would make sense due to being able to change the external one every...
