not sure whats wrong with my car but its leaking oil between the head and the block. Can anyone help me or no what it could be? its leaking right above the engine code. any help would be greatly appreciated

 

haha.. same problem, i installed my head w/o an O ring or dowel or something... so its leaking, but no problems... i rev past 8000 everyday and its been leaking for a few months... so i wouldnt worry too much. but im assuming its either blown, or just installed poorly like mine gl

whats blown? arent you loosing alot of oil

 

If it's a DOHC B engine than it's gonna be the "exhaust cam end plug".
They only last so long. Happens to all DOHC B engines eventually.
Make sure you get the superceeded P/N P72 plug, with o-ring... NOT the P30.

as 4crx4me stated there is an updated cams eal that has an o ring design, i dont belive that the oil is coming from in between the head and the block, its probably either coming from that cam seal or the distrivutor o ring try those first before you tear off your head

 

someone break this down to me...what does a cam seal have to do with oil leaking from inbetween the block/head? this seems to be a poor head gasket seal around the oil return drains on the front side of the block. cam seals leak oil from the ends of the cam, ie: cam pulleys.

this is where a touch of copper spray comes in handy...right around the oil drain holes.

hey noob, dont be recommending copper spray becasue that is the death of all honda headgaskets, and the reason im saying cam seal is maybe the cretor of this topic didnt look clsoe enough casue honda head gaskets dont often leak

wait its called P/N P72 plug with o-ring is that the exhaust cam end plug. Ill try this out first maybe its the problem. how do i change the plug?

 

you replace the plug by removing the valve cover and then removing the far bottom left hand corner cam tower cap if you are facing the engine and the seal should lift out

#1 Because if there was an oil "leak" at the headgasket bad enough to run down the front of the engine, the "oil leak" would be the least of your problems AND but a minor symptom.
#2 Experience shows me, that that's the most likely source for oil dripping down the front of the block. Or as elusiveacclude(sp?) said, it could be the dizzy o-ring as well or both. If it's a VTEC it could also be VTEC sol. seal.
#3 If you look close you can see the wet spot and trail from under those seals, they are far more likely the cause than a bad HG.
#4 The seals you are talking about are on the other SIDE of the engine. And are called "cam pulley seals". They rarely leak as they are more protected from the elements.

The Part/Number fot the newer cam seal is P72 a la TypeR. Don't let them sell you a P30, it's been superceeded.

 

if its not the plug, have you recently swapped vavlecovers or for whatever reason removed you vavle cover? if so you are supposed to replace all the seals. if not, you will get a slight leak goin and notice some oil on the ground in ur garage and what not. its not likw SPEWING oil, but its enough to notice.

 

Head Gasket Leak is my guess. Do you feel a difference in power? That area is common for head gasket leaks.

 

FOR THE LAST TIME HONDA HEADGASKETS RARELY LEAK ITS 99.9% THE CAM SEAL OR DIZZY O RING

 

noob? please, ive done more honda work than you will in your life. and i have only 8 posts less.

i never said spray the entire gasket with copper seal, just the area around the oil return gulleys. those two little tabs on opposite sides on the front of the block can use it. they have a tendency to leak, i know this, ive been building honda engines for years.
if the head gasket leaks here, you dont have a Major problem, just an oil problem. major head gasket problems take place between the cylinder and water jackets, not an oil passage and the outside of the block.

the creator of this topic said oil was leaking above the badge, from the head/block. this would lead a reader to think that the problem is a head gasket not sealing around the oil return galleys at the front of the block.

if oil was leaking from a valve cover, i think she would notice it running down her head, to the block, then down the block, collecting dirt on its path towards the ground.

read that...then think. please.

10,000 rpm OEM bottom end, built by me.

 

at first i thought the oil was coming out of my head and block but my friend told me that it wasn't so i kept looking around and its coming from the vavle cover or near the valve cover the oil drips and lands on the engine code. It doesnt drip at idle i only see oil when i drive it, so should i replace the exhaust cam end plug and the vavlecover seal? do you think the person at honda will know what im talking about when i ask for these parts cause sometimes they dont know.

 

Yes they will know, trust me.
Get a exhaust cam SEAL and get a valve cover GASKET.... Not a valve cover seal. Seals sre round, gaskets are flat.

 

wow im impressed by a b16 thats good to what 10 k there good to that stock goober and ask any factory honda tech what copper spray does, and i was assuming becasue of the questiont hat maybe the creator didnt look hard enough, and id do valve cover gasket and cam seal for the other guy

 

thanks everyone hopefully this works

 

Just get new gaskets for you head man! you may need to replace them anyways. Loosing any amount of oil is bad for you engine and may cause blown motors and HP loss. Gaskets are cheap so hook yourself up man, and do it right!!!

I think your stupid and have no clue to what your doing. You'er perhaps the same guy that ***** up his **** so many times and ends up redoing it 300 more tiimes. When in truth, you only have build one and repair that one many, many, many and still going. I've been a tech for 15 years - you can't possible have build more engines than me. You back yard hack. and everyone else

 

how many b16's do you know of that can withstand 10k rpm for longer than 15 continous minutes? im talking about an engine that endured a 600 mile trip at top speed. basically, a race. it started with 240 psi and ended with 205, across the head.

yeah, hi, youre a tech...you learn how to fix cars, not build engines. ive built many engines. d16/17 hybrids, d16 n/a's, b16 n/a's, b16 turbo, b18c, and h22's. ive also rebuilt 50cc and 100cc 2 stroke engines, lawn mower engines.
but first of all, learn how to read. i never said spray the entire gasket, just the tabs.

 

firts off to 500hpsi, i have a clue just a slight one though, while working for BMW i have rebuilt many customers motors that couldnt afford it etc etc. i build motors for my friends and customers all the time. i also didn't know backyard hacks used clean rooms to assemble there motors.

to rab honda that is imprsssive be more detailed about what your saying, and i ahve built plenty of motors b16 b18 h22 ford 4.6 5.0 chevy small small blocks from 327 to 350, and all im saying is i dont agree with copper spray period.

if i **** up my **** so many times why do i just buy new **** if it breaks. last time a motor blow i bought a new one money isnt the issue hear and if i do build somehtign it is done right the first time
