rebuilt motor valves tapping bad 5.7

Re: rebuilt motor valves tapping bad 5.7

out of couriosity, with the engine roughly level, what's the oil level now that it's been sittin for a bit?

went to take it out today second ride to break in motor.

what was the oil level prior to that run too? i still can't think that adj. the valves would spit a qt. of oil out and i ain't heard if it was found in the bilge to confirm that's where it went.......

Re: rebuilt motor valves tapping bad 5.7

oil was 1 qt low prior to 2nd run. no apparent leaks. thsi is the first qt i added since i got it back. i was thinking maybe they did not fill it correctly.
engine is level while adjusting valves and oil went in blidge

Re: rebuilt motor valves tapping bad 5.7

How did the dealer screw it up? Did the dealer screw up the valve adj. to begin with? If he did, then why didn't u take it back to him & tell him to get it right? You probably have no recourse now, since you been doing the adj. yourself & you also may have screwed up. I'm not trying to be a wise guy, but I think your in over your head. Am I correct that a dealer put a new or rebuilt engine in & you've been messing with it? Don't tell me that.

i brought a rebuilt motor,
gave it to a merc shop, the shop from hell, they had boat for 6 months and gave it back to me all wrong, drive would not go down, bad bellows etc..i had to take boat back as they killed it. i went to consumer affair and the bottom line is . they said to bring it back to finish engine,,i cring when i even think of this guys shop. when my new starter and fly turn i even get a sound like that was put on incorrect..tons of stuff wrong..if i ruined a cam, so be it as i will fix it...if i have to sell it or drop a new motor in it myself..but reguardless me and the shop are going to court. 4k labor and some parts and in bad shape...

Re: rebuilt motor valves tapping bad 5.7

delsol, do them guys drink? some mechanics like there beer. before i sold my boat for a case a coors i did some real dumb things. like the time i ran her aground in 12 inches a water an tried to pull her off with my v.w. almost fipped the beetle when i gunned it. i ain't lived that one down yet. look around yer boat for empty coors bottles. maybe the guys that worked on her were smashed when they did the work. how bout you, did ya knock down a few before ya did the valve adj? i ain't a wise guy just wonderin. i remember the time i was doin the timing an got the wires to the timing lite on assbackwards to the battry an fried it. had to buy my ex a new timin lite. boy was she mad an went after me with her breaker bar. i'm just sayin folks do some dumb stunts.

Re: rebuilt motor valves tapping bad 5.7

i ran it steady for a couple hours at about 2k rpm's on muffs, when i got it back from dealer it would not even idle. now it runs great but taps bad

you got taken bad.i just installed a new reman 5.0 long block for a guy with 1 new manifold and gimbal brg.,oil, plugs etc,for 1400.00.he paid 1200.00 for the motor.runs great.you should definatly find someone else that knows what to do.

Re: rebuilt motor valves tapping bad 5.7

HOw long did you have it idling before you got it to run good enought to break-in the cam at 2000RPM's for 2hrs?

Maybe the cam got damaged in the initial troubleshooting frenzy??

Re: rebuilt motor valves tapping bad 5.7

a hour or more at least, because i was given the boat back with 2 valves to tight . no compression. electric choke set wrong and it would not idle below 2k rpms. till i did all the steps to try to get it right...whats the worst case. new cam. that can be replaced in the boat right...intake rod's etc...i got all the tool's it started out as a job to get fixed by auth dealer. but i got screwed simple as. we are going to court soon. but i will fix it one way or another...it runs great., i was thinking to try to adjust the valves again..its a sharp boat. we are going away today for 4 days. i got so much time tied up in this boat it makes me sick..worst case r+r motor..i fixed everything else. all my bolt on's are new.i drove don and others nuts with this boat. i told my buddy friday this sucker gone and he said i was crazy..great guy who was a boss at recon engine company, but not an engine mechanic...this saga make you think that those cheap bayliners are not that bad..part of me wants to cut my losses and the other part says all that time only a little more...the motor was idleing by me a while while i checked things out , but who knows how long he ran boat in his shop..temp is great oil psi is great voltage great..runs great just taps like an old chevy. lots of guys here think i am stupid, i got lots of car backround..had at least 100 cars age 45...i have changed heads. oil pumps. timing chains..axles, you name it. but i got into a real bad position on this one

Re: rebuilt motor valves tapping bad 5.7

I`m willing to bet the cam and lifters are shot. Get new ones put them in set the valves right, break in cam and enjoy your boat. I dont know if you can do this in your boat of not. I know I have the room to do it in mine Good Luck. I`m sure it will all work out.

what are the symtoms of a bad cam??? and what happens if you still run boat???

 

[delsol]

Re: rebuilt motor valves tapping bad 5.7

if the cam wore bad. the valves would not rise. right??? and could not hurt piston. just long term running would hurt motor??? because i might after trying to adjust valves. give it 2 runs to an island close by. and relax. then pull it over the winter
any replys will help..if you do a search on me i got a purple heart over this project..injured...in action..the sad way i paid dealer to do it..it like smashing a car up..if you did it you say ok. well. but when someone else does it you are like i should have never......

Re: rebuilt motor valves tapping bad 5.7

I couldn?t read all the thread. It was bringing up to many bad memories.
Look bud, you got taken. We all have (those that don?t admit it are lying to themselves). At least its only the top end. You have a cam or lifter issue. It happens. I built my motor this winter and I am having a issue with my cam/lifters. I know I broke it in properly and did all the right things for start up. Still get a tap after running it hard (4500+) and then coming to a stop. I am convinced that I have had a bad lifter from the start. This will be the second time it has happened in the last 10 years right out of the box. I am not happy about it but there is no reason to toss the boat.
Installing a cam in a 350 is a piece of cake. Any mechanic can do it. Remember it?s a car motor. If you can not do it yourself then get it to someone who can when you have the money. He11 there may even be a few folks on here close to you that could help you out for a few bucks.
So take a few steps back and regroup. Realize that your motor journey is not over yet but you are a lot closer to the end then you are the beginning.
You want to feel real pain? A buddy of mine bought a jet boat off of eBay this spring and was on his 3rd motor on the same tank of gas. The first to go was a motor he had been building for 3 years and I?m sure he had 10 grand into it (the reason he bought the boat). One blast and it through a rod and broke the block. Looked like a Nascar motor explosion. Then fully rebuilt the motor that cam out of it originally. It lasted about a half hour. BOOOOOOMMMM. It was toast. Through a junkyard motor in it (he runs a tow yard) and almost finished the tank when it started smoking. He sold the boat last week for $200. Now he wishes he would have kept it (and he should have). I told him he to wait but he didn?t listen.

Re: rebuilt motor valves tapping bad 5.7

Ayuh,.......

Only a Guess,..... But.......
It sounds like the Cam wasn't properly broken in,+ is on it's way Out......

Thats what I'm betting on.
