    API 'SM' Oil - no zinc... don't use in old engines?

    Holy crap!!! Nobody wants to relive something like that. Did the metal shavings plug your oil filter or get into the rest of the engine? I bought ZDDP Plus online - it was expensive ($8/bottle) but I figure it's good insurance. I'll look at the O'Reily's stuff too. I readjusted my rocker...

    API 'SM' Oil - no zinc... don't use in old engines?

    My undestanding after reading the article in Mustang Monthly is that API Grade 'SM' has NO zinc in it at all and should not be used without a ZDDP additive in flat tappet engines such as ours..... So, when I buy oil, I am going to make sure I get 'SL' as long as it's available. Once it's...

    API 'SM' Oil - no zinc... don't use in old engines?

    I just saw an article in Mustang Monthly about how API Grade 'SM' oil has no zinc in it and therefore is not suitable for our flat tappet equipped engines.... I checked my stock of oil and found 4 bottles of 'SM' - the rest is all 'SL'... not sure if the missing 8 quarts of SM went in the '69...

    New Wheels - what size tires fit my car?

    Looks like I'll try option 1: 225/60R15 front, 245/60R15 rear... I'll play around with a mockup before purchasing tires though to make sure they will fit. Thanks...

    Engine Block machine work - whats the minimum to have done?

    For what's it's worth, I bought my .030" over SpeedPro hyperutectic (sp) pistons with coated skirts - complete with rings on ebay for about $100. I got a set of rebuilt, shot peened rods from PAW. Not too expensive and plenty strong for a 'warmed over' 289.

    stumbly 351w please help

    Describe your PCV sustem. If you don't have sufficient vacuum to suck out the blow by, you'll push oil out. How many miles on the engine? When I friend of mine rebuilt his 351, he had to put pcv valves on both valve covers to keep it from pushing oil out for a few hundred miles - just until...

    New Wheels - what size tires fit my car?

    After checking the available sizes in the BFG, Firestone and Good Year tires with raised white letters, the options apear to be the following: 225/60R15 on 15x7 rim 245/60R15 on 15x8 rim or 235/60R15 on 15x7 rim 255/60R15 on 15x8 rim I'm curious if the 235 is too wide/tall for the...

    New Wheels - what size tires fit my car?

    Yea, I am favoring option 2 as well - although I think 255/55's are rare. Since the wife paid for 1/2 the car I have to respect her opinion and she hates the look of 'big and little' tires... she wants them to all look the same from the side... so... I was trying to keep the sidewall height the...

    oooh... I found the chart... I'll check it out and maybe that will answer my question. I would still like to know what others with a stock suspension setup run on their 15" rims... Thanks.

    New Wheels - what size tires fit my car?

    I picked up a set of 15" Magnum 500's recently and want to find out what size tires will work on my '69 Sportsroof. The front will be 7" wide and the rear will be 8" wide. I believe both have a 4.5" back spacing. The wheels and tires I have now are 215/70R14 - overall height is 656.6 mm or...

    Will this wheel/tire combo fit my '69???

    Why does my starter continue to turn the engine even after I remove the key?

    Yes it was the solenoid.... I should have stopped and thought about it more before tearing into it... I had the starter off and replaced the ignition switch before realizing that it was the stupid solenoid. I know better than that. For some reason I thought the solenoid was integral to the...

    Why does my starter continue to turn the engine even after I remove the key?

    I fired up my '91 GT today and it made a strange whine so I turned it off. That's when I realized that the starter was running and was engaged. I removed my key and the starter kept running - turning over the engine. I had to unhook the battery to stop it. I figured i had a stuck starter...

    Valve float problem?

    When I say 'goose' the engine, I mean quickly open the throttle so the RPM's go up. What is the advance when the engine is running at a constant 2000 rpm.

    Valve float problem?

    Just goose the engine (W/ SPOUT out) and see if the timing goes up to about 36 degrees total at 2,000 rpm. If not, phutch11 is probably on to something. Change should be about ~26 degrees (~10 at idle to ~36 at 2,000 rpm). Detonation = pinging = a loud clatter that sounds like a diesel...

    Valve float problem?

    If you pulled the SPOUT connector and you're still running 26 advanced, I'm shocked that the car will even start... or run without detonation. Are you sure you pulled the SPOUT? You should set initial timing around 12 degrees. Oh yea, are you sure you pulled the SPOUT????

    Need Help w/ Sound Insulation for '65 Coupe

    I work at Ford and have responsibility for sound insulators and carpet on several programs. When it comes to sound insulation, the method of control depends on the source and the frequency of the sound. Low frequency sounds (suspension noise, engine noise, exhaust) respond well to mass...

    options for engine bay paint/coatings

    I used POR-15 in black. It's a pretty moderate level of gloss. I tried to top coat it with POR15 'Chassis Black' (which has more gloss) but it was too think to spray so I was stuck with the basic black POR-15 since I didn't have the proper thinner. It's not UV stabilized like chassis black is...

    Rebuild questions

    Did they at least hone the cylinders so your new rings will seat? They look kind of shiney in the picture.... if not, stop what you're doing and have them honed. Can't remember the proper cross hatch angle for moly rings but I'm sure someone will...
