Car Forum / Honda Cars / February 20061990 ACCORD LX OIL LEAK DISTRUBUTOR
Hi folks, Maybe someone can shed some light on this problem. 1990 Accord LX 4 door auto. Oil pouring out of vent hole at bottom of distributor. Not the O ring seal. OK This happened last June 20 2005 After 198,000 miles it emptied the oil pan in 50 miles of driving. On the way home from work about 5 miles from home. Oil light comes on, pull over shut down engine check oil, dip stick dry. WTF !!! Luckily I had just bought the oil for a oil change that weekend in the trunk. Dump it in, check it almost a gallon used. Start it up check it oil, pouring out of distributor. Drive like hell to get it home. At home closer inspection shows it pouring out of the vent hole at bottom of distributor. Ok, Remove disassemble and inspect. Disassembling distributor and the oil seal at the bottom was pushed out of the its seat in the lower housing. Ok, seal looked dried out and cracked. Probably age replacement should fix it up. Sleeve bearing was fine. I'll replace it. After a ridiculous local search for the oil seal I found one place on the net with OEM seals. Pressed new seal in, good to go. Assembled tested, lasted exactly 20 minutes oil pouring out again ! WTF !! Disassembled, oil seal pushed back out. Everybody is telling me " You cant fix them you got to replace the distributor " OK, I'll replace it. Search Local Bone yards, Not one Honda car in the yard with this type of model still on the car ! Is there a pattern here ? Found a replacement ( rebuilt ) Good to go. Installed and set up fine. Today 1 30 2006 216,000 miles on clock On the way home from work again. Oil light comes on about 20 miles from home, pull over shut down engine. Lift hood ,oil smell. oil all over top of starter. Check oil on stick. empty, Oh No not again. Lucky I keep a spare gallon in trunk, Fill it up. Start engine, oil pouring out of vent hole again. Drive like hell to get home again. Hopefully this distributor has a warranty so it goes back. What is wrong with this CAR ? What have I over looked on this car. Any suggestions would be a help. I am beginning to loose my faith in this car Thanks John Sounds like a problem with engine ventilation. Just my 2¢ worth.. JT > Hi folks, > [quoted text clipped - 54 lines] > Thanks > John > Sounds like a problem with engine ventilation. Just my 2¢ worth.. Hey, good one. John, when was the last time you checked the PCV valve, for one? With the car idling, I would first pinch its intake line shut with pliers and cloth wrapped around the line. Do you hear a click from the valve within 30 seconds? If not, definitely replace it, and that tells you that the valve may very well be the problem. If you do hear a click, indicating some kind of operation, but maybe not adequate operation, then next remove and inspect the PCV valve and the lines connecting to it, along with the other crankcase breathing lines. If either the valve or lines are chock full of waxy, oily debris, that may indicate the crankcase is being overpressurized, leading to the oil leaks. A new seal would hold only so long. Clean the lines as best you can. Replace the PCV valve and its grommet. (Old grommets can crack and produce vacuum leaks.) These parts are cheap--under $20 or so at www.slhonda.com . They are shown under engine, yada, then "Breather Tube." > Sounds like a problem with engine ventilation. Just my 2¢ worth.. Ditto. PCV system is plugged.  SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ Well It must be plugged at highway speed cause it aint plugged at idle. Ever seen a PCV close up at highway speed ? Is there a possibility this thing does something not normal at highway speed? when valve is pulled from cover there is air flow from crankcase. Valve is working and there is plenty of vacuum at ilde. Line is dry with no signs of oily/waxy/sludge residue in hose. Engine appears to idle smoothly with no rough or varing idle speed. No check engine warning lights or such either. Grommet fits valve snuggly. Engine does not burn oil and there does not seem like any noticeable blowby. But something is not right. Why for almost 200,000 miles no problem and then bingo within 6 months its blowing seals. problem with rear cam bearing ? high oil flow ? no noticeable noises comming form head or engine. But why does the bearing on the distrubutor not show signs of distress, if cam bearing was loose and sloppy. Can valve tappet adjustment cause this ?

Ever seen a PCV close up at highway speed ? No, but I've seen engines with blowby that's too great for the PCV system to handle. > Is there a possibility this thing does something not normal at highway > speed? Heaviest air flow is at larger throttle openings. That's when the PCV valve is working its hardest. > when valve is pulled from cover there is air flow from crankcase. > Valve is working and there is plenty of vacuum at ilde. > Line is dry with no signs of oily/waxy/sludge residue in hose. There might be sludge partially plugging up the oil separator box or rocker cover baffling (whichever your car has). > Engine appears to idle smoothly with no rough or varing idle speed. A plugged PCV by itself will have no effect on idle on vehicles with a feedback system. > No check engine warning lights or such either. > Grommet fits valve snuggly. But what about the breather tube? The one that goes from the rocker cover to the intake pipe, that is. Also check for oil in the big air pipe to the throttle body. > Engine does not burn oil You can't tell.

Lots is not. > But something is not right. That's for sure. > Why for almost 200,000 miles no problem and then bingo within 6 months > its blowing seals. Everything here points to a breathing problem. Check the PCV SYSTEM, NOT just the valve. If the entire system is clear and there's no oil in the big air pipe, then there's something else wrong. Possibilities: The O-ring is the wrong size, made of the wrong material, or is installed incorrectly. Did the O-ring come from the dealer or Home Depot? > problem with rear cam bearing ? high oil flow ? no noticeable noises > comming form head or engine. > But why does the bearing on the distrubutor not show signs of > distress, The distributor bearing is not lubricated by engine oil. > Can valve tappet adjustment cause this ?

Good point. Rotate cam so those lobes are off the lifters, then pull the bearing cap. You should be able to see the crosshatching. If it's gone, there may be considerable wear. Cam wear on these engines is the result of infrequent oil changes, or engines where the oil level has been repeatedly run too low. > blocked pcv can also blow a seal, but it'll oil from /all/ the seals, > not just one. Eventually yes, but it often starts at the weakest one.
