Paking Silinder Head Mendadak Bocor

Post by herbid »

Apa kira2x penyebab utama hingga paking mendadak bocor?

Sebelumnya mobil normal, tdk overheat, konsumsi bensin normal, speed dan power standar (tidak ngempos), idle 700 rpm tidak pincang.

Dan bagaimana cara untuk mendeteksi bahwa Paking Silinder Head sudah perlu diganti?
Berdasarkan km atau tahun pemakaian?

Terimakasih.

sebenernya ada beberapa faktor jg sih oom....untuk mesin2 yg sudah lama khususnya, selain usia komponen...material fatique... dll

penumpukan kerak di ruang bakar jg semakin lama membuat vol ruang bakar menyempit....efeknya yaitu rasio kompresi membesar krn penyempitan volume tsb...hal ini berefek beban tekanan yg ditahan oleh paking semakin besar....setelah kurun waktu tertentu bisa merembes...

saya sendiri kurang mengetahui metode apa untuk menentukan kapan paking tsb harus diganti (periodik)....krn umumnya sih awet2 ajah...biasanya penggantian dilakukan saat ada pengerjaan seputar cyl-head atau turun mesin

cuma itu yang saya tahu...mohon dikoreksi lagi dari pakar2 disini..... :big_peace:

mungkin om TS bsa memberikan info lbh lengkap mengenai data2 kendaraan yg d maksud( thn/jenis dll), lalu pd saat kapan/apa kebocoran terjadi/d ketahui....

biar nantinya rekan2 lain lbh mudah melakukan analisa2 dugaan penyebab kebocoran itu..... :ungg: :ungg:

klo pengalaman sy, kemungkinannya bsa jg krn usia pakai yg sdh waktunya...ato beban kerja mesin yg sedikit d paksa berada pd level stres tinggi scr konstan-simultan...............akhirnya bocor deeeeh :mrgreen: :mrgreen: :mrgreen:

Thx atas masukannya,
tetapi kronologis sebenarnya adalah sbb:

Ternyata didapati bahwa Pipa besi di "Rumah" thermostat - tempat selang air dicolokkan - karat dan keropos,
maka air keluar ketika panas, lama2x habis dan suhu mobil sempat naik.

Akhirnya, kenalpot keluar air, mesin pincang dan oli tercampur air.

Diputuskan mesin diturunkan 1/2 dan mengganti semua paking serta bikin baru pipa yg keropos tadi.

Selesai sekitar jam 12-an, perjalanan pulang dari Bandung ke Jakarta Via Tol,
rasanya cocok untuk dijadikan ajang "Super Duper' Test BBM dengan HCS.

Cuaca siang itu cukup mendung bersahabat,
setelah isi full tank menjelang pinto tol Cimahi,
mobil menyusuri jalan tol dg kec rata2x 70 - sesekali 80, tanpa ac.

Sesampainya di Jakarta tercatat jarak tempuh 140 Km,
dan untuk isi full tank lagi ternyata "Hanya" butuh 8,5 liter ......

Dihitung-hitung,
konsumsi kijang 1800 tuwir yang masih 4 speed ini adalah (dengan HCS tentunya):
1lt : 16,5 Km.

Sekian live reportnya.

Ralat dikit,
ternyata kronologisnya mesin sudah pincang lebih dulu (karena kemasukan air dari paking yg bocor),
air kemudian bekurang, mesin panas.

Saat dibetulkan baru ditemukan ada pipa air yang keropos,
tapi hanya bocor rembes sedikit.

Sampai dengan tahap ini,
penyebab paking silinder bocor berarti bukan dari panas atau air yang bocor.

Dugaan sementara,
mobil dikebut .........
