Question:
I've got a 61 beetle with a 71 engine, and I just did a engine overhaul (new machined valves, pistons, cylinders) we also have a brand new empi weber-clone Carb, and the gas is getting in the crankcase now,
any possible reasons?
Answers:
Where is the thermostat on a Northstar engine?
I would suggest replacing the fuel pump. You might luck out, and that would be the quickest and cheapest fix.how many years did oldsmobile put out the cutlass gt?
sounds like piston rings. Or bad machining with the cylinders or something... Whats interesting is that the gas isnt burning. Could have some serious issues with that enginecheck engine code fro 1996 grand voyager?
Bad rings on one or more pistons. Check each cylinder's compression to look for one that's way low.replace the gas pump, or put outside the motor an electrical one
how much does it cost to tax a 2.0 litre vauxhall vectra? for 6 months? or 12 months?
I think that maybe the float needle isnt working properly and fuel is steadily going through the carb even though it isnt getting burned.When you had the engine apart. did you check to see if it had a cracked block?
It sounds like it might have a cracked block.
The first thing to do with any engine overhaul is to check for a cracked block. If it's cracked, junk it and buy a rebuilt or new block.
my car is a 1995 nissan altima..and i am changing the alternator?
I would look at my fuel pump. But if you overhauled it, I KNOW you did put a new fuel pump in. Even if your carbareutor leaked gas, there is no way for it to get to the oil. Now replace the oil in the morning and drive it around all day with no chance of anyone tampering with it and find if you have gas in it. Look at ALL possibilities if the the fuel pump is not the answer. That is the only way for fuel to get in the oil, THE ONLY WAY.The other 2 answers are correct but add the possibility of carb problems IE: flooding, too much gas to the cylinders. You didn't state how it runs. good luck
buick rond. changed thermostat still not heating up?
You didn't say if the engine actually RUNS.If it runs I am surprised you can detect the gas since the engine heat would vaporize it even if it made it to the crankcase.
does anyone know where i can find a turbo kit for a fiat punto sporting 1.2 16v (2001)?
Soooo I suspect that the engine will not run.
If it is that much gas that you can notice it, I would suspect the carb is dumping it into the manifold.... if you have the old carb put it back on and see if the problem goes away. Thats an easy thing to check before you move on to the rings and such.

wich car is the fastest in the world?
Ok.. so it DOES run and you swapped out the carb with no real change.

Next check your cylinder compression. All 4 should be about equal and around 110 psi. If any single cylinder is different by a lot (20+ lbs) then you have a ring or valve problem.
Only answer if you own or know someone who owns a 2002 dodge stratus.?
How do you know you are getting gas in there (see the part about evaporation)?
Timing could be doing this too. If your spark is firing at the wrong time or one cylinder is not firing at all, that gas is going to go down between the rings as well as out the exhaust..
Others have commented on the fuel pump and this is an easy thing to check.... put the old one back on and try again.

The diaphragm in the fuel pump is ruptured or needs spacing.too much carb , if its set rich or is otherwise leaking fuel into the engine, the new rings aren't fully seated and the gas ends up in the oil . go through the carb again and change the oil , then take it on the highway and let the engine get warm , check your oil after the highway run , keep an eye on this , hopefully your rings seat soon and a leaner setup on the carb helps , also run it on the highway at least once a week , short trips kill !
question for JOHN PAUL!! PLEASE HELP!!!?
It is a very easy thing to do when going back with the stock fuel pump setup on a fresh rebuild. I had it happen to one of my club members. Putting a new offbrandname fuel pump on a rebuild you run the risk of still mismatching the pump to rod issue. what probably happend is that new fuel pump is for a generator rod instead of an alternator one. That mix up for sure will result on some cases a ruptured fuel pump diaphram or worst destruction of the pump itself. MY advice, stay with vw made or sponsered product when doing any parts replacement. Try changing that fuel pump and you should be fine.Good luck.Is a RFL BOV too loud for a wrx sti?
what you have is trash in your gas tank. your carbs. both old and new have trash inside them, the needle vavles are allowing fuel to overflow into engine. flush tank, install a good fuel filter, clean carbs.drain oil and refill,you'll be fine.More Questions & Answers ...
